A01920 (F) PROFIBUS: Interruption cyclic connection
Message value: -
Message class: Communication error to the higher-level control system (9)
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.
Note:
If there is no communication to a higher-level control system, then p2030 should be set = 0 to suppress this
message.

Reaction upon F: NONE (OFF1)
Acknowl. upon F: IMMEDIATELY
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]).
