The motor controller CMMD-AS-C8-3A provides the functionality of 2 motor controllers in one housing.
The connection designations of the motor controller provide an assignment for connections to axes
(
Fig. 2.3 and Fig. 2.4). Connections with the index '1' are assigned to axis 1 (e.g. [X1.1], connections
with index '2' to axis 2 (e.g. [X1.2]. Connections that are used together do not have an index. The fol-
lowing connections are therefore available once and are used together:
–
[X9] Power supply and braking resistor
–
[X4]: CAN bus
–
[X5]: RS232/RS485.
In this documentation the index '1/2' is written whenever both connections are meant. [X1.1/2] stands
for connection [X1.1] and [X1.2].
