Introduction

The Motion Control MForce MicroDrive offers system
designers a low cost, intelligent motion controller integrated
with a +12 to +48 volt/2A RMS Output Current microstep-
ping drive and Motion Controller.
The unsurpassed smoothness and performance delivered
by the Motion Control MForce MicroDrive 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 MForce MicroDrive accepts a broad input voltage range
from +12 to +48 VDC, 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.
Standard features available in the MForce MicroDrive include four +5 to +24 volt general purpose I/O lines, one
10 bit analog input, 0 to 5MHz step clock rate, 20 microstep resolutions up to 51,200 steps per revolution, and full
featured easy-to-program instruction set.
Expanded features in the MForce MicroDrive Plus 2 version
include eight +5 to +24 volt general purpose I/O lines and the
capability of electronic gearing by following a rotary or linear axis
at an electronically controlled ratio, or an output clock can be
generated fixed to the internal step clock.

closed loop control. This increases functionality by adding stall
detection, position maintenance and find index mark. The closed
loop configuration offers an expanded choice of line counts and
resolutions by interfacing to a remotely mounted user-supplied
external encoder.
The Motion Control MForce MicroDrive communicate over
RS-422/485 which allows for point-to-point or multiple unit
configurations utilizing one communication port. Addressing and
hardware support up to 62 uniquely addressed units communi-
cating over a single line. Baud rate is selectable from 4.8 to 115.2kbps.
Power and signal interface connections are accomplished using 12.0" (30.5cm) flying leads or a 7 position terminal
strip. Plus 2 versions interface using a pluggable locking wire crimp connector. Motor phases are connected via a
pluggable 4-pin locking wire crimp connector.
The MForce MicroDrive is a compact, powerful and inexpensive solution that will reduce system cost, design and
assembly time for a large range of applications.
