Status of CAN axis synchronisation using the UserLED

Question:
How can the status of drive synchronisation via CAN sync be seen from 'outside'?

Answer:
In applications with master value selection via CAN (e. g. electrical shaft), it is often important that the control programs of the drive controllers start synchronously. An asynchronous behaviour appears, for instance, as a 'clicking' noise in the machine because the speed setpoint 'zero' is sporadically detected for a bus transmission cycle (discontinuous speed characteristics) leading to corresponding reactions in the motor control.

The following interconnection allows you to detect the status of CAN axis synchronisation quickly and easily:
