I n t e r f a c i n g P o w e r

An advantage of the MDrive Motion Control is that only a single +12 to +48VDC unregulated linear or unregulated switching power supply is required to power the control circuitry and motor power.

A maximum of 2A output is required from the supply for each MDrive. Note that the actual power required will be based upon the load and duty cycle.

Wiring should be accomplished using shielded twisted pair Belden Part# 9740 or equivalent 18 Gauge. The shield should be attached to earth at the power supply end and left floating at the MDrive end.

The MDrive Motion Control communicates to the host using the RS-485 protocol. Communications may be configured as either half or full duplex using the EM (Echo Mode) Instruction. RS-485 may be used in two ways: either to communi- cate to a single MDrive Motion Control, or to address up to 62 individually named MDrive nodes in a multidrop system.

Optionally available for the MDrive Motion Control is a communications cable, IMS P/N MD-CC200-000, which has built-in RS-232 to RS-485 conversion circuitry. This will allow you to connect the serial port of your PC directly to the MDrive Motion Control.
