1.4.2 Communication Interfaces
1.4.2.1 CAN
Both drive amplifiers are connected to the PCB’s CAN-bus connector. Please use the following components for the
CAN-bus connection:
• Housing: TE Connectivity, HE14 receptacle double row 8 circuits, 281839-4
• Contacts: TE Connectivity, HE14 crimp terminal female 28-24 AWG, 182734-2
The pin assignment is as follows:

If the CAN bus ends at one of the Omni-Drive-Modules a terminating resistor of 120
Ω
has to be activated. Please
move switch S1 beside the LEDs to position ON.
1.4.2.2 RS-232
Each drive amplifier has a separate RS-232-interface which can be used for configuration and for communication with
the control software.
