Module 2CAN

Usable with S300, S600, S700


Connector X6 of the servo amplifier is assigned to the signals for the RS232 interface and the CAN interface (see Connectors). It is therefore not the standard pin assignment for these interfaces, and a special cable is required to be able to use both interfaces simultaneously.

The 2CAN expansion module provides the interfaces on separate Sub-D connectors. The two CAN connectors are wired in parallel. A termination resistor (120 ohms) for the CAN bus can be switched into circuit if the  is at the end of the bus.

Standard shielded cables can be used for the RS232 and CAN interfaces.
