Schneider Electric: MDrive® Plus Programmable Motion Control (NEMA 23)

The MDrive® Plus Motion Control is a 1.8° 2-phase stepper motor with on-board fully programmable motion controller, drive electronics and optional encoder. This means MDrive Plus Motion Control products are stand-alone motion control solutions that can be used without any external controller.

MDrive products come standard with RS-422/485 serial interface. Programming is with MCode, simple 1 to 2 character instructions, using the IMS Terminal software tool.

Size 23 MDrive products are also available for Modbus/TCP protocol. Programming is with the same MCode instruction set used for the RS-422/485 products. Modbus/TCP products support the application protocol per specification Version 1.1b, with operation in immediate mode, not as programmable products.

MDrive Plus Motion Control products may be equipped with encoders for stall detection, position maintenance and find index mark.

Application Areas:

The MDrive Plus Motion Control is ideal for machine builders who want an optimized motor with on-board electronics. The integrated electronics of the fully programmable MDrive Plus Motion Control reduces the potential for problems due to electrical noise by eliminating the cable between motor and drive.

These compact, powerful and cost effective motion control solutions deliver unsurpassed smoothness and performance that will reduce system cost, design and assembly time for a large range of 2-phase stepper motor applications.
