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 120 ohm termination resistor is present between CAN_H and CAN_L. Supply the controller with voltage. Change the configuration values if necessary, see configuration CANopen. The controller is set per default to node-ID 1, baud rate 1 Mbaud. 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.
