Motor control MST 102

Allows the 3 point controller MST 101 to be operated with a stepper motor as actuator.

  • For bipolar step motors up to 2A phase current
  • Phase current monitoring adjustable (chopper)
  • Two speeds selectable (Jumper)

Connection Diagram MST 102

The phase current is set at the setting resistor (top). After removal of the terminal cover (bottom left) the jumper is accessible for changing the speeds.
Orbital period:
  • Jumper open; 12 sec / revolution
  • Jumper set; 6 sec / revolution
  • Further speeds are possible by arrangement
