4 Faults and alarms
4.2 List of faults and alarms
F07443 (A) LR: Reference point coordinate not in the permissible range
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The reference point coordinate received when adjusting the encoder via connector input p2599 lies outside the half of
the encoder range and cannot be set as actual axis position.
Fault value (r0949, interpret decimal):
Maximum permissible value for the reference point coordinate.
Remedy: Set the reference point coordinate to a lower value than specified in the fault value.
See also: p2598 (EPOS reference point coordinate signal source), p2599 (EPOS reference point coordinate value)
F07450 (A) LR: Standstill monitoring has responded
Message class: Application/technological function faulted (17)
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: After the standstill monitoring time (p2543) expired, the drive left the standstill window (p2542).
- position actual value inversion incorrectly set (p0410).
- standstill window set too small (p2542).
- standstill monitoring time set too low (p2543).
- position loop gain too low (p2538).
- position loop gain too high (instability/oscillation, p2538).
- mechanical overload.
- Connecting cable, motor/drive converter incorrect (phase missing, interchanged).
- when selecting motor identification, select tracking mode (BI: p2655[0] = 1 signal).
Remedy: Check the causes and resolve.
F07451 (A) LR: Position monitoring has responded
Message class: Application/technological function faulted (17)
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: When the position monitoring time (p2545) expired, the drive had still not reached the positioning window (p2544).
- positioning window parameterized too small (p2544).
- position monitoring time parameterized too short (p2545).
- position loop gain too low (p2538).
- position loop gain too high (instability/oscillation, p2538).
- drive mechanically locked.
Remedy: Check the causes and resolve.
F07452 (A) LR: Following error too high
Message class: Application/technological function faulted (17)
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The difference between the position setpoint position actual value (following error dynamic model, r2563) is higher
than the tolerance (p2546).
- the drive torque or accelerating capacity exceeded.
- position measuring system fault.
- encoder cable interrupted.
- position control sense incorrect.
- mechanical system locked.
- excessively high traversing velocity or excessively high position reference value (setpoint) differences
Remedy: Check the causes and resolve.
