A01053 CU: System overload measured
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: A system overload was determined based on measured values.
Alarm value (r2124, interpret decimal):
2: Computation time load too high.
6: Cyclic computation time load too high.
See also: r9976 (System load)
Remedy: - reduce the sampling time.
- only use one data set (CDS, DDS).
- de-activate the function module.
- de-activate the drive object.
- remove the drive object from the target topology.
A01064 (F) CU: Internal error (CRC)
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: CRC error in the Control Unit program memory
Remedy: - carry out a POWER ON (power off/on) for all components.
- upgrade the firmware release.
- contact the Hotline.
Reaction upon F: A_INFEED: NONE (OFF1, OFF2)
SERVO: NONE (OFF1, OFF2, OFF3, STOP2)
VECTOR: NONE (OFF1, OFF2, OFF3, STOP2)
Acknowl. upon F: IMMEDIATELY (POWER ON)
A01065 Drive: Fault for non-active encoder
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: On or several inactive encoders indicate an error.
Remedy: Remove the error for the inactive encoder.
A01099 Tolerance window of the timer synchronization exited
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The clock (time) master exited the selected tolerance window for clock synchronization.
See also: p3109 (RTC real time synchronization, tolerance window)
Remedy: Select the re-synchronization interval so that the synchronization deviation between the clock master and drive sys-
tem lies within the tolerance window.
See also: r3108 (RTC last synchronization deviation)
A01100 CU: CompactFlash card withdrawn
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The CompactFlash card (non-volatile memory) was withdrawn in operation.
Notice:
It is not permissible that the CompactFlash card is withdrawn or inserted under voltage.
Remedy: - power-down the drive system.
- re-insert the CompactFlash card that was withdrawn - this card must match the drive system.
- power-up the drive system again.
