Siemens SINAMICS S210 - Clock Cycle Synchronous Operation Clock Cycle Failure; Clock Cycle Synchronous Operation Sign-Of-Life Failure; Clock Cycle Synchronous Operation Sign-Of-Life Failure Drive Object

Remedy: - Adapt the bus parameterization Tdp, Ti, To.
- adapt the sampling time for the current controller or speed controller.
For alarm value = 10:
- reduce Tdx by using fewer bus participants or shorter telegrams.

F01911 (N, A) PB/PN: clock cycle synchronous operation clock cycle failure
Message value: -
Drive object: All objects
Reaction: Servo: OFF1 (OFF3)
Acknowledge: IMMEDIATELY
Cause: The global control telegram to synchronize the clock cycles has failed - in cyclic operation - for several DP clock cycles or
has violated the time grid specified in the parameterizing telegram over several consecutive DP clock cycles (refer to the
bus cycle time, Tdp and Tpllw).
Remedy: - check the physical bus configuration (cable, connector, terminating resistor, shielding, etc.).
- check whether communication was briefly or permanently interrupted.
- check the bus and controller for utilization level (e.g. bus cycle time Tdp was set too short).

F01912 (N, A) PB/PN: clock cycle synchronous operation sign-of-life failure
Message value: -
Drive object: All objects
Reaction: Servo: OFF1 (OFF3)
Acknowledge: IMMEDIATELY
Cause: The maximum permissible number of errors in the controller sign-of-life (clock synchronous operation) has been exceeded
in cyclic operation.
Remedy: - physically check the bus (cables, connectors, terminating resistor, shielding, etc.).
- correct the interconnection of the controller sign-of-life (p2045).
- check whether the controller correctly sends the sign-of-life (e.g. create a trace with STW2.12 ... STW2.15 and trigger
signal ZSW1.3).
- check the permissible telegram failure rate (p0925).
- check the bus and controller for utilization level (e.g. bus cycle time Tdp was set too short).
