The MDrive NEMA 23 high torque Integrated Motor and Driver is ideal for designers who want the simplicity of a motor with on-board electronics, but without the ex- pense of an indexer on each axis. The low cost MDrive23 allows the system designer to decide the best method of control. The MDrive23’s integrated electronics eliminate the need to run the motor cabling through the machine, reducing the potential for problems due to elec- trical noise.

The MDrive23 uses a NEMA 23 frame size 1.8° high torque step- ping motor combined with a mic- rostepping driver, and accepts up to 14 resolution settings from ½ to 256 microsteps per full step. Setup parameters include Micro- step Resolution, Motor Run/Hold Current, and Motor Direction with respect to the direction input. 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. Operating voltage for the MDrive23 ranges from +12 to +48 VDC or +24 to +75 VDC.

The versatile, compact MDrive23 is available in multiple configurations to fit various system needs. These include a single shaft rotary mo- tor, a dual shaft rotary motor available with optical encoder or control knob, a planetary gearbox, or a long life Acme screw linear actuator. The rotary MDrive23 is available in single, double and triple stack sizes: 18, 22 & 31. Interface

connections are accomplished us- ing either a 12 position keyed and locking pin and receptacle (C Con- nector), a 7 position terminal strip, or 12.0" (30.5cm) flying leads.

The MDrive23 is a compact, pow- erful and inexpensive solution that will reduce system cost, design and assembly time for a large range of stepping motor applications.

CONFIGURING

The IMS Motor Interface software is an easy to install and use GUI for configuring the MDrive23 from a computer parallel/SPI port. GUI access is via the IMS SPI Inter- face included on the CD shipped with the product, or download at www.imshome.com. Optional cables are available for ease of connecting and configuring the MDrive.

The IMS 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 setting for each option.

•Single screen interface (below).

The IMS Motor Interface GUI simplifies MDrive configuring with a single screen interface. (DIR feature with C Connector version only.)
