Faults and alarms
List of faults and alarms
Remedy: Note:
PB: PROFIBUS
PN: PROFINET
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
A01920 (F) PROFIBUS: Interruption cyclic connection
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The cyclic connection to the PROFIBUS master is interrupted.
Remedy: Establish the PROFIBUS connection and activate the PROFIBUS master in the cyclic mode.
Reaction upon F: NONE (OFF1)
Acknowl. upon F: IMMEDIATELY
A01921 (F) PROFIBUS: Receive setpoints after To
Message value: -
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 clock cycle clock cycle synch. not equal
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The current controller clock cycle 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 clock cycle.
Remedy: Set current controller clock cycles to identical values (p0115[0]).
Note:
PB: PROFIBUS
PN: PROFINET
A01931 PB/PN speed controller clock cycle clock cycle synch. not equal
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The speed controller clock cycle 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 clock cycle.
