Assignment of the CAN interface on the frequency inverter
The 24V supply for the absolute encoder and the CAN Bus/CANopen interface must be provided via an
external supply. For the assignment of the terminals, please refer to the encoder manufacturer´s operating
instructions.
Table 11: Contact assignment for the RJ45 interface
NOTE
Recommendation: To provide strain relief, the CAN cable can be connected to the screening
angle of the EMC Kit (option). Details of the EMC Kit can be found in the BU0500 manual.
