4 Faults and alarms
4.2 List of faults and alarms
A01921 (F)
PROFIBUS: Receive setpoints after To
Message value:
-
Message class:
Communication error to the higher-level control system (9)
Drive object:
All objects
Reaction:
NONE
Acknowledge:
NONE
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
Reaction upon F:
NONE (OFF1)
Acknowl. upon F:
IMMEDIATELY
A01930
PB/PN current controller sampling time clock cycle synch. not equal
Message value:
%1
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Drive object:
All objects
Reaction:
NONE
Acknowledge:
NONE
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]).
Note:
PB: PROFIBUS
PN: PROFINET
See also: p0115
A01931
PB/PN speed controller sampling time clock cycle synch. not equal
Message value:
%1
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Drive object:
All objects
Reaction:
NONE
Acknowledge:
NONE
Cause:
The speed 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 the different speed controller sampling time.
Remedy:
Set the speed controller sampling times to identical values (p0115[1]).
Note:
PB: PROFIBUS
PN: PROFINET
See also: p0115
A01940
PB/PN clock cycle synchronism not reached
Message value:
-
Message class:
Communication error to the higher-level control system (9)
Drive object:
All objects
Reaction:
NONE
Acknowledge:
NONE
Cause:
The bus is in the data exchange state and clock synchronous operation has been selected using the parameterizing
telegram. It was not possible to synchronize to the clock cycle specified by the master.
