Diagnosis / Faults and Alarms
Alarm value 10: Impermissible length of an optional parameterization block
(r2124): 11: Impermissible ID of an optional parameterization block
20: Duplicate parameterization block for isochronous operation
21: Errored parameterization block for isochronous operation
22: Errored parameterization bits for isochronous operation
Remedy: Check the bus configuration:
- Bus addresses
- Slave configuration
A1902
PROFIBUS: Parameterizing telegram not permitted
Cause: -
Alarm value 0: Bus cycle time Tdp < 1 ms
(r2124): 1: Bus cycle time Tdp > 32 ms
2: Bus cycle time Tdp is not a whole multiple of the current control clock cycle.
3: Time of actual value recording Ti > Bus cycle time Tdp
4: Time of actual value recording Ti is not a whole multiple of the current control clock cycle.
5: Time of setpoint transfer To > Bus cycle time Tdp
6: Time of setpoint transfer To is not a whole multiple of the current control clock cycle.
7: Master application cycle time Tmapc is not a whole multiple of the speed control clock
cycle.
8: Bus reserve bus cycle time Tdp - data exchange time Tdx less than two current controller
clock cycles.
9: Bus cycle time Tdp changed compared to first connection setup.
Remedy: - Adapt parameterizing telegram.
- Adapt current or speed control clock cycle.
F1910
PROFIBUS: Setp. Timeout
Reaction: OFF1
Cause: The receipt of setpoints from the PROFIBUS interface is interrupted because the bus
connection is interrupted or the PROFIBUS master is switched off or in the STOP state.
Remedy: Restore the bus link and set the PROFIBUS master to RUN.
Acknowl.: Immediate
F1911
PROFIBUS: Clock synchronous clock failure
Reaction: OFF1
Cause: The global control telegram for synchronizing the clock cycles has failed in cyclic mode for
several DP clock cycles or has violated the specified time grid specified in the
parameterization telegram over several consecutive DP clock cycles (see bus cycle times
Tdp and Tpllw).
Remedy: - Check PROFIBUS cable and plug-in connections.
- Check whether the communication interruption is short-term or permanent.
- Check bus or master. for overload (e. g. bus cycle time Tdp set too short).
Acknowl.: Immediate
F1912
PROFIBUS: clock synchronous sign of life
Reaction: OFF1
Cause: The maximum permissible number of sign-of-life failures on the master (isochronous
PROFIBUS) has been exceeded in cyclic operation.
Remedy: - Correct the connection of the master sign of life (p2045).
- Check whether the signal of life is being transmitted correctly by the master.
- Check the permissible failure rate of telegrams (p0925).
- Check bus or master for. for overload (e. g. bus cycle time Tdp set too short).
Acknowl.: Immediate
F1920
PROFIBUS: Interruption in cyclic link
Reaction: OFF1
Cause: The cyclic link to the PROFIBUS master is interrupted.
Remedy: Set up the PROFIBUS link and activate PROFIBUS master in cyclic mode.
Acknowl.: Immediate
