4.4.3 Motor
As motor connector a 4pin connector is available. The motor connector is used for connecting the four motor
wires of the two motor coils of the bipolar stepper motor to the electronics.
Do not connect or disconnect motor during operation!
Motor cable and motor inductivity might lead to voltage spikes when the motor is
disconnected / connected while energized. These voltage spikes might exceed voltage
limits of the driver MOSFETs and might permanently damage them. Therefore, always
disconnect power supply before connecting / disconnecting the motor.

4.4.4 Mini-USB
A 5pin mini-USB connector is available on-board for serial communication (as alternative to the CAN and RS485
interface). This module supports USB 2.0 Full-Speed (12Mbit/s) connections.
CAN interface will be de-activated as soon as USB is connected due to internal sharing of hardware
resources.

Table 4.7 Connector for USB
For remote control and communication with a host system the PD42-x-1140 provides a USB 2.0 full-speed
(12Mbit/s) device interface (mini-USB connector). As soon as a USB-Host is connected the module will accept
commands via USB.
