SECTION 1.1
Introduction to the MDrive34AC Plus Microstepping
The MDrive34AC Plus Microstepping high torque inte-
grated motor and driver is ideal for designers who want the
simplicity of a motor with on-board electronics. The inte-
grated electronics of the MDrive34AC Plus eliminate the
need to run motor cabling through the machine, reducing
the potential for problems due to electrical noise.
The unsurpassed smoothness and performance delivered by
the MDrive34AC Plus Microstepping are achieved through
IMS's advanced 2nd generation current control. By apply-
ing innovative techniques to control current flow through
the motor, resonance is significantly dampened over the
entire speed range and audible noise is reduced.
The MDrive34AC Plus accepts a broad input voltage range
from 95 to 264 VAC, delivering enhanced performance
and speed. Oversized input capacitors are used to minimize
power line surges, reducing problems that can occur with
long runs and multiple drive systems. An extended operat-
ing range of –40° to +85°C provides long life, trouble free
service in demanding environments.
Figure 1.1.1: MDrive34AC Plus Microstepping Integrated
Motor, Power Supply, and Drive Electronics
The MDrive34AC Plus uses a NEMA 34 frame size high torque brushless motor combined with a microstepping
driver, and accepts up to 20 resolution settings from full to 256 microsteps per full step, including: degrees, metric
and arc minutes. These settings may be changed on-the-fly or downloaded and stored in nonvolatile memory with
the use of a simple GUI which is provided. This eliminates the need for external switches or resistors. Parameters
are changed via an SPI port.
For use in environments where exposure to dust and liquids may occur, a sealed MDrive34AC Plus Microstepping
unit with circular connectors meets IP65 specifications.
The versatile MDrive34AC Plus Microstepping is available in multiple configurations to fit various system needs.
Three rotary motor lengths are available as are optional: internal optical encoder; control knob for manual po-
sitioning; integrated planetary gearbox. A long life Acme screw linear actuator version is also available. Interface
connections are accomplished using standard industrial connectors.
The MDrive34AC Plus is a compact, powerful and inexpensive solution that will reduce system cost, design and
assembly time for a large range of brushless motor applications.
Configuring
The IMS Motor Interface software is an easy to install and use GUI for configuring the MDrive34AC Plus from a
computer's USB port. GUI access is via the IMS SPI Motor Interface included on the CD shipped with the prod-
The IMS SPI Motor Interface features:
Easy installation.
Automatic detection of MDrive version and communication configuration.

SECTION 1.3
Introduction to the MDrive42AC Plus Microstepping
The MDrive42AC Plus Microstepping high torque
integrated motor and driver is ideal for designers
who want the simplicity of a motor with on-
board electronics. The integrated electronics of the
MDrive42AC Plus eliminate the need to run motor
cabling through the machine, reducing the potential
for problems due to electrical noise.
The unsurpassed smoothness and performance
delivered by the MDrive42AC Plus Microstepping
are achieved through IMS's advanced 2nd generation
current control. By applying innovative techniques
to control current flow through the motor, resonance
is significantly dampened over the entire speed range
and audible noise is reduced.
The MDrive42AC Plus accepts a broad input voltage
range from 95 to 264 VAC, delivering enhanced
performance and speed. Oversized input capacitors
are used to minimize power line surges, reducing
problems that can occur with long runs and multiple
drive systems. An extended operating range of –40°
to +85°C provides long life, trouble free service in
demanding environments.
Figure 1.3.1: MDrive42AC Plus Microstepping Integrated
Motor, Power Supply, and Drive Electronics
The MDrive42AC Plus uses a NEMA 42 frame size high torque brushless motor combined with a microstepping
driver, and accepts up to 20 resolution settings from full to 256 microsteps per full step, including: degrees, metric
and arc minutes. These settings may be changed on-the-fly or downloaded and stored in nonvolatile memory with
the use of a simple GUI which is provided. This eliminates the need for external switches or resistors. Parameters
are changed via an SPI port.
For use in environments where exposure to dust and liquids may occur, a sealed MDrive42AC Plus Microstepping
unit with circular connectors meets IP65 specifications.
The versatile MDrive42AC Plus Microstepping is available in multiple configurations to fit various system needs.
Two rotary motor lengths are available as are optional: internal optical encoder; control knob for manual position-
ing; integrated planetary gearbox. Interface connections are accomplished using standard industrial connectors.
The MDrive42AC Plus is a compact, powerful and inexpensive solution that will reduce system cost, design and
assembly time for a large range of brushless motor applications.
Configuring
The IMS Motor Interface software is an easy to install and use GUI for configuring the MDrive42AC Plus from a
computer's USB port. GUI access is via the IMS SPI Motor Interface included on the CD shipped with the prod-
The IMS SPI Motor Interface features:
Easy installation.
Automatic detection of MDrive version and communication configuration.
Will not set out-of-range values.
Tool-tips display valid range

SECTION 2.1
Logic Interface and Connection
Optically Isolated Logic Inputs
The MDriveAC Plus
Microstepping has three
optically isolated logic
inputs which are located
on connector P1. These
inputs are isolated to
minimize or eliminate
electrical noise coupled
onto the drive control
signals. Each input is
internally pulled-up to
the level of the optocou-
pler supply and may be
connected to sinking or
+5 to +24 VDC sourcing
outputs on a controller or
PLC. These inputs are:

Of these inputs only step clock and direction are required to operate the MDriveAC Plus Microstepping.
Isolated Logic Input Pins and Connections
The following diagram illustrates the pins and connections for the MDriveAC Plus Microstepping family of prod-
ucts. Careful attention should be paid to verify the connections on the model MDriveAC Plus Microstepping you

Isolated Logic Input Characteristics
Enable Input
This input can be used to enable or disable the driver output circuitry. Leaving the enable switch open (Logic
HIGH, Disconnected) for sinking or sourcing configuration, the driver outputs will be enabled and the step clock
pulses will cause the motor to advance. When this input switch is closed (Logic LOW) in both sinking and sourc-
ing configurations, the driver output circuitry will be disabled. Please note that the internal sine/cosine position
generator will continue to increment or decrement as long as step clock pluses are being received by the MDriveAC
Plus Microstepping.
Clock Inputs
The MDriveAC Plus Microstepping features the ability to configure the clock inputs based upon how the user will
desire to control the drive. By default the unit is configured for the Step/Direction function.
Step Clock
Step/Direction Function
The step clock input is where the motion clock from your
control circuitry will be connected. The motor will advance
one microstep in the plus or minus direction (based upon
the state of the direction input) on the rising edge of each
clock pulse. The size of this increment or decrement will
depend on the microstep resolution setting.
Step Clock
Direction
Direction
The direction input controls the CW/CCW direction
of the motor. The input may be configured as sinking or
sourcing based upon the state of the Optocoupler Refer-
ence. The CW/CCW rotation, based upon the state of the
input may be set using the IMS Motor Interface software
included with the MDriveAC Plus Microstepping.
Quadrature Function
Channel A
Channel B
Quadrature
The Quadrature clock function would typically be used
for following applications where the MDriveAC Plus
Microstepping would be slaved to an MDriveAC Plus
MicroDrive Motion Control (or other controller) in an
electronic gearing application.
Up/Down Function
Up/Down
The Up/Down clock would typically be used in a dual-
clock direction control application. This function is also
labled CW/CCW in the SPI Motor Interface software.
CW
CCW
Input Timing
The direction input and the microstep resolution inputs
are internally synchronized to the positive going edge of
the step clock input. When a step clock pulse goes HIGH,
the state of the direction input and microstep resolution
settings are latched. Any changes made to the direction
and/or microstep resolution will occur on the rising edge
Figure 2.1.2: Input Clock Functions
of the step clock pulse following this change. Run and Hold Current changes are updated immediately. The
following figure and table list the timing specifications.
Input Filtering
The clock inputs may also be filtered using the Clock IOF pull down of the IMS SPI Motor Interface. The
filter range is from 50 nS (10 MHz) to 12.9 µSec. (38.8 kHz).
The configuration parameters for the input filtering is covered in detail in Section 2.4: Configuring the
MDriveAC Plus Microstepping.

HCDT (Hold Current Delay Time)
The HCDT Motor Hold Current Delay sets time in milliseconds for the Run Current to switch to Hold Current when
motion is complete. When motion is complete, the MDriveAC Plus Microstepping will reduce the current in the windings
of the motor to the percentage specified by MHC when the specified time elapses.

MRC (Motor Run Current)
The MRC Motor Run Current parameter sets the motor run current to a percentage of the full output current of the
MDriveAC Plus driver section.
MHC (Motor Hold Current)
The MHC parameter sets the motor holding current as a percentage of the full output current of the driver. If the hold
current is set to 0, the output circuitry of the driver section will disable when the hold current setting becomes active. The
hold current setting becomes active HCDT setting mS following the last clock pulse.

SECTION 2.4
Using User-Defined SPI
The MDriveAC Plus can be configured and operated through the end-user's SPI interface without using the IMS
SPI Motor Interface software and optional parameter setup cable.
An example of when this might be used is in cases where the machine design requires parameter settings to be
changed on-the-fly by a software program or multiple system MDriveAC Plus Microstepping units parameter states
being written/read.
SPI Timing Notes
1. MSb (Most Significant bit) first and MSB (Most Significant Byte) first.
2. 8 bit bytes.
3. 25 kHz SPI Clock (SCK).
4. Data In (MOSI) on rising clock.
5. Data Out (MISO) on falling clock.

Check Sum Calculation for SPI
The values in the example below are 8-bit binary hexadecimal conversions for the following SPI parameters:
MRC=25%, MHC=5%, MSEL=256, HCDT=500 mSec, WARNTEMP=80.
The Check Sum is calculated as follows:
(Hex) 80+19+05+00+00+01+F4+50
Sum = E3
1110 0011
1’s complement = 1C
2’s complement = 1D
Send the check sum value of 1D
0001 1100 (Invert)
0001 1101 (Add 1)
Note: 80 is always the first command on a write.
Note: Once a write is performed, a read needs to be performed to see if there is a fault. The fault is the last byte of
the read.

MDrive with Planetary Gearbox
Section Overview
This section contains guidelines and specifications for MDrives equipped with an optional Planetary Gearbox,
and may include product sizes not relevant to this manual.
Shown are:
Product Overview
Selecting a Planetary Gearbox
Mechanical Specifications
Product Overview
All gearboxes are factory installed.
Mode of Function
Optional Planetary Gearbox operate as their name implies: the motor-driven sun wheel is in the center,
transmitting its movement to three circumferential planet gears which form one stage. They are arranged
on the bearing pins of a planet carrier. The last planet carrier in each sequence is rigidly linked to the out-
put shaft and so ensures the power transmission to the output shaft. The planet gears run in an internally
toothed outer ring gear.
Service Life
Depending on ambient and environmental conditions and the operational specification of the driving
system, the useful service life of a Planetary Gearbox is up to 10,000 hours. The wide variety of potential
applications prohibits generalizing values for the useful service life.
Lubrication
All Planetary Gearbox are grease-packed and therefore maintenance-free throughout their life. The best
possible lubricant is used for our MDrive/Planetary Gearbox combinations.
Mounting Position
The grease lubrication and the different sealing modes allow the Planetary Gearbox to be installed in any
position.
Operating Temperature
The temperature range for the Planetary Gearbox is between –30 and +140° C. However, the temperature
range recommended for the Heat Sink of the MDrive is 0 to +85º C.
Overload Torque
The permitted overload torque (shock load) is defined as a short-term increase in output torque, e.g. dur-
ing the start-up of a motor. In these all-metal Planetary Gearbox, the overload torque can be as much as
1.5 times the permitted output torque.
Available Planetary Gearbox
The following lists available Planetary Gearbox, diameter and corresponding MDrive.

Selecting a Planetary Gearbox
There are many variables and parameters that must be considered when choosing an appropriate reduction
ratio for an MDrive with Planetary Gearbox. This Addendum includes information to assist in determining a
suitable combination for your application.

combination, but is a calculated value that includes an operating factor (C ) to compensate for any shock
B
loads applied to the Planetary Gearbox due to starting and stopping with no acceleration ramps, payloads and
directional changes. The main reason the shock load output torque (T ) is calculated is to ensure that it does
not exceed the maximum specified torque for a Planetary Gearbox.
AB
Note: There are many variables that affect the calculation of the shock load output torque. Motor speed, motor
voltage, motor torque and reduction ratio play an important role in determining shock load output torque.
Some variables must be approximated to perform the calculations for the first time. If the result does not meet
your requirements, change the variables and re-calculate the shock load output torque.
Use the equation compendium below to calculate the shock load output torque.

Operating Factor - A value that is used to factor the shock load output torque.
Safety Factor - A 0.5 to 0.7 factor used to create a margin for the MDrive torque
requirement.
Reduction Ratio
Reduction ratio (i) is used to reduce a relatively high motor speed (nM) to a lower output speed (nAB).
With: i = nM ÷ nAB or: motor speed ÷ output speed = reduction ratio
Example:
The required speed at the output shaft of the Planetary Gearbox is 90 RPM.
You would divide motor speed (nM) by output speed (nAB) to calculate the proper gearbox ratio.
The MDrive speed you would like to run is approximately 2000 full steps/second or 600 RPM.
NOTE: In reference to the MDrive speed values, they are given in full steps/second on the Speed/Torque
Tables. Most speed specifications for the Planetary Gearbox will be given in RPM (revolutions per min-
ute). To convert full steps/second to RPM, divide by 200 and multiply by 60.
Where: 200 is the full steps per revolution of a 1.8° stepping motor.
2000 full steps/second ÷ 200 = 10 RPS (revolutions per second) × 60 Seconds = 600 RPM
For the Reduction Ratio (i), divide the MDrive speed by the required Planetary Gearbox output speed.
600 RPM ÷ 90 = 6.67:1 Reduction Ratio
Referring to the Available Ratio Table at the end of this section, the reduction ratio (i) of the Planetary
Gearbox will be 7:1. The numbers in the left column are the rounded ratios while the numbers in the
right column are the actual ratios. The closest actual ratio is 6.75:1 which is the rounded ratio of 7:1. The
slight difference can be made up in MDrive speed.

Nominal Output Torque
Calculate the nominal output torque using the torque values from the MDrive’s Speed/Torque Tables.
Nominal output torque (TN) is the actual torque generated at the Planetary Gearbox output shaft which
includes reduction ratio (i), gear efficiency (η) and the safety factor (sf) for the MDrive. Once the reduction
ratio (i) is determined, the nominal output torque (TN) can be calculated as follows:
TN = TM × i × η ÷ sf or:
Motor torque × reduction ratio × gear efficiency ÷ safety factor = nominal output torque.
For gear efficiency (η) refer to the Mechanical Specifications for the 7:1 Planetary Gearbox designed for
your MDrive.
For motor torque (TM) see the appropriate MDrive Speed/Torque Table. Dependent on which
MDrive you have, the torque range will vary. The torque will fall between the high voltage line and the low
voltage line at the indicated speed for the MDrive. (See the example Speed/Torque Table below.)

Figure B.1: MDrive23 Torque-Speed Curve
The Speed/Torque Table above is for an MDrive23 Double Length Motor. This MDrive will produce a
torque range of 51 to 95 oz-in in the full voltage range at the speed of 2000 Full Steps/Second (600 RPM).
Please note that this is not the usable torque range. The torque output to the Planetary Gearbox must
include a safety factor (sf) to allow for any voltage and current deviations supplied to the MDrive.
The motor torque must include a safety factor (sf) ranging from 0.5 to 0.7. This must be factored into the
nominal output torque calculation. A 0.5 safety factor is aggressive while a 0.7 safety factor is more conser-
vative.
Example:
The available motor torque (TM) is 51 to 95 oz-in.
NOTE: You may specify a torque less than but not greater than the motor torque range.
For this example the motor torque (TM) will be 35 oz-in.
A 6.75:1 reduction ratio (i) has been determined.
Gear efficiency (η) = 80% from the appropriate table for the Planetary Gearbox which is used
with an MDrive23.
Nominal output torque would be:
Motor torque (TM = 35) × reduction ratio (i = 6.75) × gear efficiency (η = 0.8) ÷ safety factor (sf
= 0.5 or 0.7)
35 × 6.75 = 236.25 × 0.8 = 189 ÷ 0.5 = 378 oz-in nominal output torque (TN)
or
35 × 6.75 = 236.25 × 0.8 = 189 ÷ 0.7 = 270 oz-in nominal output torque (TN)
With the safety factor (sf) and gear efficiency (η) included in the calculation, the nominal output torque
(TN) may be greater than the user requirement.

Shock Load Output Torque
The nominal output torque (TN) is the actual working torque the Planetary Gearbox will generate. The
shock load output torque (TAB) is the additional torque that can be generated by starting and stopping
with no acceleration ramps, payloads, inertia and directional changes. Although the nominal output
torque (TN) of the Planetary Gearbox is accurately calculated, shock loads can greatly increase the dy-
namic torque on the Planetary Gearbox.
Each Planetary Gearbox has a maximum specified output torque. In this example a 7:1 single stage
MD23 Planetary Gearbox is being used. The maximum specified output torque is 566 oz-in. By calculat-
ing the shock load output torque (TAB) you can verify that value is not exceeding the maximum specified
output torque.
When calculating the shock load output torque (TAB), the calculated nominal output torque (TN) and the
operating factor (CB) are taken into account. CB is merely a factor which addresses the different working
conditions of a Planetary Gearbox and is the result of your subjective appraisal. It is therefore only meant
as a guide value. The following factors are included in the approximate estimation of the operating factor
(CB):
Direction of rotation (constant or alternating)
Load (shocks)
Daily operating time
Note: The higher the operating factor (CB), the closer the shock load output torque (TAB) will be to the
maximum specified output torque for the Planetary Gearbox. Refer to the table below to calculate the
approximate operating factor (CB).
With the most extreme conditions which would be a CB of 1.9, the shock load output torque (TAB) is
over the maximum specified torque of the Planetary Gearbox with a 0.5 safety factor but under with a 0.7
safety factor.
The nominal output torque (TN) × the operating factor (CB) = shock load or maximum output torque
(TAB).
With a 0.5 safety factor, the shock load output torque is greater than the maximum output torque specifi-
cation of the MDrive23 Planetary Gearbox.
(378 × 1.9 = 718.2 oz-in.)
With a 0.7 safety factor the shock load output torque is within maximum output torque specification of
the MDrive23 Planetary Gearbox.
(270 × 1.9 = 513 oz-in.)
The 0.5 safety factor could only be used with a lower operating factor (CB) such as 1.5 or less, or a lower
motor torque.
Note: All published torque specifications are based on CB = 1.0. Therefore, the shock load output torque
(TAB) = nominal output torque (TN).
WARNING! Excessive torque may damage your Planetary Gearbox. If the MDrive/Planetary Gearbox
should hit an obstruction, especially at lower speeds (300 RPM or 1000 Full Steps/Second), the torque
generated will exceed the maximum torque for the Planetary Gearbox. Precautions must be taken to
ensure there are no obstructions in the system.

System Inertia
System inertia must be included in the selection of an MDrive and Planetary Gearbox. Inertia is the resistance
an object has relative to changes in velocity. Inertia must be calculated and matched to the motor inertia. The
Planetary Gearbox ratio plays an important role in matching system inertia to motor inertia. There are many
variable factors that affect the inertia. Some of these factors are:
The type of system being driven.
Weight and frictional forces of that system.
The load the system is moving or carrying.
The ratio of the system inertia to motor inertia should be between 1:1 and 10:1. With 1:1 being ideal, a 1:1 to
5:1 ratio is good while a ratio greater than 5:1 and up to 10:1 is the maximum.
Type of System
There are many systems and drives, from simple to complex, which react differently and possess varied
amounts of inertia. All of the moving components of a given system will have some inertia factor which
must be included in the total inertia calculation. Some of these systems include:
Lead screw
Rack and pinion
Conveyor belt
Rotary table
Belt drive
Chain drive
Not only must the inertia of the system be calculated, but also any load that it may be moving or carrying.
The examples below illustrate some of the factors that must be considered when calculating the inertia of a
system.
Lead Screw
In a system with a lead screw, the following must be considered:
The weight and preload of the screw
The weight of the lead screw nut
The weight of a table or slide
The friction caused by the table guideways
The weight of any parts
Weight of
table

Once the system inertia (JL) has been calculated in oz-in-sec , it can be matched to the motor inertia. To
match the system inertia to the motor inertia, divide the system inertia by the square of the gearbox ratio.
The result is called Reflected Inertia or (Jref).
2
Jref = JL ÷ Ζ
Where:
2
JL = System Inertia in oz-in-sec
2
Jref = Reflected Inertia in oz-in-sec
Z = Gearbox Ratio
The ideal situation would be to have a 1:1 system inertia to motor inertia ratio. This will yield the best
positioning and accuracy. The reflected inertia (Jref) must not exceed 10 times the motor inertia.
Your system may require a reflected inertia ratio as close to 1:1 as possible. To achieve the 1:1 ratio, you
must calculate an Optimal Gearbox Ratio (Zopt) which would be the square root of JL divided by the
desired Jref. In this case since you want the system inertia to match the motor inertia with a 1:1 ratio, Jref
would be equal to the motor inertia.
Zopt
=
JL ÷ Jref
Where:
Zopt = Optimal Gearbox Ratio
JL = System Inertia in oz-in-sec
2
2
Jref = Desired Reflected Inertia in oz-in-sec (Motor Inertia)

Determining the Virtual COM Port (VCP)
The MD-CC300-000 uses a Virtual COM Port to communicate through the USB port to the MDrive. A VCP is a
software driven serial port which emulates a hardware port in Windows.
The drivers for the MD-CC300-000 will automatically assign a VCP to the device during installation. The VCP
port number will be needed when IMS Terminal is set up in order that IMS Terminal will know where to find and
communicate with your IMS Product.
To locate the Virtual COM Port.
1) Right-Click the “My Computer” Icon and select “Properties”.
2) Browse to the Hardware Tab (Figure C.8), Click the Button labeled “Device Manager”.
3) Look in the heading “Ports (COM & LPT)” IMS USB to SPI Converter Cable (COMx) will be listed
(Figure C.9). The COM # will be the Virtual COM Port connected. You will enter this number into
your IMS SPI Motor Interface Configuration.
