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.

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- uct, 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.

Automatic detection of MDrive version and communication configuration.

Will not set out-of-range values.

Tool-tips display valid range setting for each option.

Simple screen interfaces.
