11.11.1. CANopen ® Fieldbus Connector

The CANopen ® communications board is provided with a 9pin male “D” connector. The bus interface circuitry is internally supplied, as prescribed by the CANopen ® specifications.

Pins are arranged as follows:

CAUTION

The CANopen connector is the same type as the connector fitted in all the drives series for the Modbus serial communications, but the pin layout and the internal circuitry are totally different. Make sure that connectors are not mismatched! A wrong connection of the CANopen connector to the Modbus interface or vice versa can damage the inverter and the other devices connected to the Modbus and CANopen networks.

11.11.2. Board Configuration

The CANopen communications board shall be used with three rotary-switches for configuration, which are required to set up the inverter operating mode. The rotary-switches also allow setting the baud rate and the

Device Address. The figure below shows the position of the rotary-switches and a setting example with a baud rate of 125kbits/s and a Device Address equal to 29.

NOTE

Device Address = 0 is not allowed by the CANopen specifications. Values ranging from 1 to 99 can be selected.
