4 Connectors
The PD20-1-1210 offers two connectors including the motor connector which is used for connecting the
motor coils to the electronics. The other five pin connector combines power supply input, RS485 2-wire
communication interface and one digital input which can be used as general purpose digital input but,
also as end or reference switch input for the motin controller.
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.
