6 MSE570 Stepper Drive

The MSE570 stepper drive translator is a 3.5A per phase bi-polar stepper drive.
The clock and direction signals from the PM600 controller are converted into chopped,
constant current drive levels to energise a bipolar stepper motor.
The step sequence is set to

half step

. Using a hybrid type stepper motor, 400 steps per

revolution will be obtained.
A thermal sensor protects the output devices in case of overheating. If the drive
temperature exceeds 80

°

C, the thermal sensor will operate. With the switch settings

shown below, the drive is disabled (SW1-1=on) and the condition is latched (SW1-2=on).
The latched condition can only be reset by removing the power.
