F07451 LR: Position monitoring has responded
Message class: Application/technological function faulted (17)
Message value: -
Component: None
Response: OFF1
Acknowledgment: IMMEDIATELY
Cause: When the position monitoring time (p2545) expired, the drive had still not reached the positioning window (p2544).
- P
ositioning window par
ameterized 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 LR: Following error too high
Message class: Application/technological function faulted (17)
Message value: -
Component: None
Response: OFF1
Acknowledgment: IMMEDIATELY
Cause: The di󹪜er
ence be
tween 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) di󹪜erences.
Remedy: Check the causes and resolve.
F07453 LR: Position actual value preprocessing error
Message class: Application/technological function faulted (17)
Message value: -
Component: None
Response: OFF1
Acknowledgment: IMMEDIATELY
Cause: A position measuring system fault has occurred (F31110, F31111).
An err
or has occurr
ed during the position actual value preprocessing.
Remedy: Resolve the cause of the position measuring position fault.
Check the encoder f
or the position actual value preprocessing.

A07454 LR: Position actual value preprocessing does not have a valid encoder
Message class: Error in the parameterization / con󹪝guration / commissioning pr
ocedure (18)
