Modular Stepper Motor Controller (MSMC Series)

Modular Controller Configurations

The MSMC integrated stepper motor controller provides a cost effective solution to a wide range of applications that require accurate manipulation of the driven mechanism. The MSMC incorporates a less sophisticated software interface to that of the SMC range.

A user friendly command line interface is used to communicate to the MSMC via a host computer. The commands are inputted as a string of ASCII characters that can then be transferred via the RS232 or RS485 connection to the controller. A number of strings can be stored in the MSMC's on-board memory to form a sequence of moves that can be triggered by the available inputs.

Simply connect the intelligent drive to a PC, motor, travel limits etc, and an AC power supply using cables provided, and the system is fully operational.
