A01983 PN: system redundancy switchover running
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: All objects
Component: None Propagation: LOCAL
Reaction: NONE
Acknowledge: NONE
Cause: The "PROFINET system redundancy" function is configured and the connection between the primary control and
drive device is interrupted. The backup controller assumes control of the drive device.
Remedy: Not necessary.
The alarm is automatically withdrawn after switchover has been successfully completed.
A01989 PN: internal cyclic data transfer error
Message value: %1
Message class: Communication error to the higher-level control system (9)
Drive object: All objects
Component: None Propagation: LOCAL
Reaction: NONE
Acknowledge: NONE
Cause: The cyclic actual values and/or setpoints were not transferred within the specified times.
Alarm value (r2124, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: Correctly set T_io_input or T_io_output.
A01990 (F) USS: PZD configuration error
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: All objects
Component: None Propagation: LOCAL
Reaction: NONE
Acknowledge: NONE
Cause: The configuration of the process data (PZD) for the USS protocol is incorrect.
Alarm value (r2124, interpret decimal):
2: PZD amount (p2022) too great for the first drive object (p978[0]).
The number of possible PZD items in a drive object is determined by the number of indices in r2050/p2051.
Remedy: For alarm value = 2:
Check the amount of USS PZD (p2022) and the maximum PZD amount (r2050/p2051) for the first drive object
(p0978[0]).
Reaction upon F: NONE (OFF1)
Acknowl. upon F: IMMEDIATELY
A02000 Function generator: Start not possible
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: All objects
Component: None Propagation: BICO
Reaction: NONE
Acknowledge: NONE
Cause: The function generator has already been started.
Remedy: Stop the function generator and restart again if necessary.
Note:
The alarm is reset as follows:
- remove the cause of this alarm.
- restart the function generator.
