A01943 alarm in siemens 6RA80 DC Drive indicate that the clock cycle signal error when establishing bus communication. This means the bus is in the data exchange state and clock synchronous operation has been selected using the parameterizing telegram.

  1. Check the master application and bus configuration.
  2. Check the consistency between the clock cycle input when configuring the slave and clock cycle setting at the master.
