Ministep power stages for two-phase stepper motors
The power stages type MSX are used for bipolar control of two-phase stepper motors with
phytron’s welltried technology, now with enhanced 4 quadrant chopper type current
control.
Run and stop current can be set by rotary switches. Overdrive, Boost, Activation and
Motor direction are activated by DIP switches.
Step resolution and phase current shape can be set by a rotary switch, too:
1/1, 1/2, 1/4, 1/5, 1/10 and 1/20 of a full step.
