Cyclic modes

In cyclic synchronous modes reference values are sent and updated with each EtherCAT communication frame, so a reference signal has to be sent with up to 4 kHz. As an example, to rotate the motor shaft from position A to position B in cyclic synchronous position mode within one second, the following information has to be sent to the drive:

  • position A in the beginning

  • 3998 intermediate positions (ideally at 4 kHz)

  • position B in the end
