DESCRIPTION
The Microstepping MForce PowerDrive
is a high performance, low cost microstepping driver that delivers unsurpassed
smoothness and performance achieved
through IMS’s advanced 2nd generation
current control. By applying innovative techniques to control current fl ow
through the motor, resonance is signifi cantly dampened over the entire speed
range and audible noise is reduced.
Microstepping MForce PowerDrives accept a broad input voltage range from
+12 to +75 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.
The high, per phase output current of up
to 5 Amps RMS, 7 Amps Peak, allows
the extremely compact MForce PowerDrive to control a broad array of motors
from size 23 to size 42.
The microstepping drive 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-fl y 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.
The versatile Microstepping MForce
PowerDrive comes with dual mounting
confi gurations to fi t various system needs.
All interface connections are accomplished
using pluggable locking wire crimp connectors. Optional cables are available for ease
of connecting and confi guring the MForce,
and are recommended with fi rst order.
The Microstepping
is a compact, powerful and inexpensive
solution that will reduce system cost,
design and assembly time for a large
range of applications.

CONFIGURING
The IMS SPI Motor Interface software is
an easy to in stall and use GUI for con fi g ur ing Microstepping
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.
The IMS SPI Motor Interface features:
• Easy installation.
•
Automatic detection of MForce version
and communication confi guration.
• Will not set out-of-range values.
• Tool-tips display valid range
setting for each option.
• Simple screen interfaces.
