CANopen Before starting commissioning, we recommend reading chapters Pin assignment and CANopen configuration. Connect the CANopen master to the controller via the CAN_L, CAN_H cables. Check the connection of your CAN-GND and that the necessary termination resistor is present between CAN_H and CAN_L. Supply the controller with voltage. Change the configuration values if necessary, see configuration CANopen. To test the interface, send bytes 40 41 60 00 00 00 00 00 to the controller. Statusword (6041h) was read; you receive this response: 4B 41 60 00 XX XX 00 00.
