Low parameter for SPI, changed temperature specification to: -40°C to +75°C (non-condensing humidity), measured at
the heat sink, and -40°C to +90°C (non-condensing humidity), measured on the motor.

Low Voltage Installation Information

Certain practices must be followed when installing the AC motor drives in order to meet the requirements of the Low Voltage Directive 73/23/EEC
and as amended by Directive 93/68/EEC. The AC motor drives are components intended for installation within other electrical systems or ma­chines. The system or machine builder must ensure their product complies with the applicable standards required for that equipment. The following
information applies to the AC motor drives as far as the Low Voltage Directive is concerned.

1) The AC motor drives are designed to be installed in a pollution degree level 2 environment.

2) All control inputs and outputs are isolated from AC power with a basic insulation rating. The minimum clearance and creepage distance
on the printed wiring board from the AC input to the control inputs and outputs is 3 millimeters. This is representative of an impulse
rating of 4 KV (1.2/50 us) as referenced in standard EN50178.

3) The control inputs and outputs may require an additional level of protection against direct contact if such protection is required by the
standards governing the overall system or machine and its intended environment. It is the machine builder’s responsibility to provide
this protection if needed.

4) Be sure to wire the AC power and earth ground connection as shown in the operator’s manual.

5) All cautions and warnings listed throughout the operator’s manual must be followed to insure safe system operation.

Connecting Parameter Setup Cable

Connect the Host PC to the MDriveAC Plus Microstepping using the IMS Parameter Setup Cable or equivalent.

Install the IMS SPI Motor Interface

The IMS SPI Motor Interface is a utility that easily allows you to set up the parameters of your MDriveAC Plus
Microstepping. It is available both on the MDriveAC Plus CD that came with your product and on the IMS web
site at http://www.imshome.com/software_interfaces.html.

1. Insert the CD into the CD Drive of your PC. If the CD is not available, go to http://www.imshome.
com/software_interfaces.html.

2. The CD will auto-start.

3. Click the Software Button in the top-right navigation Area.

4. Click the IMS SPI Interface link appropriate to your operating system.

5. Click SETUP in the Setup dialog box and follow the on-screen instructions.

6. Once IMS SPI Motor Interface is installed, the MDriveAC Plus Microstepping settings can be checked
and/or set.

Once installed you can change the motor run current, holding current, microstep resolution and other configura­tion settings. By sending clock pulses to the drive you can now change these settings safely on the fly as the IMS
SPI Motor interface will not allow you to set an out of range value.

MDriveAC Plus Microstepping Hardware - Revision R121707

Relevant to Firmware Version 3.0.02

SECTION 1.1

Introduction to the MDrive34AC Plus Microstepping

The MDrive34AC 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 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 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 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 operat­ing range of –40° to +85°C provides long life, trouble free
service in demanding environments.

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 po­sitioning; 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 prod­uct, or from www.imshome.com. Optional cables are available for ease of connecting and configuring the MDrive.

The IMS SPI Motor Interface features:

 Easy installation.

Relevant to Firmware Version 3.0.02

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 on­board 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.

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 position­ing; 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.

Motor, Power Supply, and Drive Electronics

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 prod­uct, or from www.imshome.com. Optional cables are available for ease of connecting and configuring the MDrive.

The IMS SPI Motor Interface features:

 Easy installation.
