3.3.1 CANopen absolute encoders
Connection of an absolute encoder is made via the internal system bus interface. As a minimum
requirement, the absolute encoder to be connected must have a CAN Bus interface with CANopen
protocol. The internal CAN Bus with CANopen protocol can be used simultaneously for control and
parameterisation as well as the readout of the absolute encoder position.
The frequency inverter supports CANopen absolute encoders with the communication profile DS 406.
Automatic parameterisation of the encoder via the frequency encoder is possible if an absolute
encoder approved by Getriebebau NORD GmbH & Co. KG is used. In this case, only the CAN
address and the baud rate of the encoder need to be set on the rotary or DIP - switches of the
encoder. All other necessary parameters are set by the frequency inverter via the CAN Bus in the
encoder.
