4 Faults and alarms
4.2 List of faults and alarms
Remedy: Restore the bus connection and set the controller to RUN.
Note regarding PROFIBUS slave redundancy:
For operation on a Y link, it must be ensured that "DP alarm mode = DPV1" is set in the slave parameterization.
F01911 (N, A) PB/PN clock cycle synchronous operation clock cycle failure
Drive object: DCP_CTRL, TM150, TM15DI_DO, TM31
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).
PB: PROFIBUS
PN: PROFINET
F01915 (N, A) PB/PN clock cycle synchronous operation sign-of-life failure drive object 1
Drive object: All objects
Cause: Group display for problems with the sign-of-life of the master (clock-cycle synchronous operation) on the drive object
1 (Control Unit).
For central measurements, synchronism with the central master is lost.
Remedy: Note:
PB: PROFIBUS
PN: PROFINET
A01920 (F) PROFIBUS: Interruption cyclic connection
Drive object: All objects
Cause: The cyclic connection to the PROFIBUS master is interrupted.
Remedy: Establish the PROFIBUS connection and activate the PROFIBUS master in the cyclic mode.
Note:
If there is no communication to a higher-level control system, then p2030 should be set = 0 to suppress this
message.
See also: p2030 (Field bus int protocol selection)
A01921 (F) PROFIBUS: Receive setpoints after To
Drive object: All objects
Cause: Output data of PROFIBUS master (setpoints) received at the incorrect instant in time within the PROFIBUS clock
cycle.
Remedy: - check bus configuration.
- check parameters for clock cycle synchronization (ensure To > Tdx).
Note:
To: Time of setpoint acceptance
Tdx: Data exchange time
A01930 PB/PN current controller sampling time clock cycle synch. not equal
Drive object: All objects
Cause: The current controller sampling time of all drives must be set the same for the clock cycle synchronous operation.
Alarm value (r2124, interpret decimal):
Number of the drive object with different current controller sampling time.
Remedy: Set current controller sampling time to identical values (p0115[0]).

PN: PROFINET
