4 Connectors
The PD42-
x
-1370 offers two connectors - one 10 pin connector for power supply, communication (RS485)
and IOs and one 4 pin connector for connecting the stepper motor.
NOTICE
Start with power supply OFF and do not connect or disconnect motor dur-
ing operation!
Motor cable and motor inductivity might lead to voltage spikes
when the motor is (dis)connected while energized. These voltage spikes might
exceed voltage limits of the driver MOSFETs and might permanently damage
them. Therefore, always switch off / disconnect power supply or at least disable
driver stage before connecting / disconnecting motor.
