SINAMICS G130/G150
1556 List Manual (LH2), 07/2016, A5E03263479A
Reaction upon A: NONE
Acknowl. upon A: NONE
F07451 (A) LR: Position monitoring has responded
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
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.
Reaction upon A: NONE
Acknowl. upon A: NONE
F07452 (A) LR: Following error too high
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
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.
Reaction upon A: NONE
Acknowl. upon A: NONE
F07453 LR: Position actual value preprocessing error
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: An error has occurred during the position actual value preprocessing.
Remedy: Check the encoder for the position actual value preprocessing.
