What it means
F07452 means that the drive's following-error monitoring (LR) has responded: the difference between the position setpoint and the position actual value — the following error of the dynamic model, shown in r2563 — is greater than the tolerance set in p2546. Depending on how the drive is configured, the same condition can also be output as an alarm (A).
Why it appears
- The drive torque or the accelerating capacity is exceeded.
- The position measuring system is faulty.
- The encoder cable is interrupted.
- The position control sense is set incorrectly.
- The mechanical system is locked.
- The traversing velocity or the differences between the position reference values (setpoints) are excessively high.
What to check
- Read the following error currently present in r2563 and compare it with the tolerance in p2546.
- Check whether the drive torque or the accelerating capacity is exceeded.
- Check the position measuring system for a fault.
- Check the encoder cable for interruption.
- Check that the position control sense is correct.
- Check whether the mechanical system is locked.
- Check whether the traversing velocity or the position setpoint differences are excessively high.
Parameters the manual names
- r2563 (CO: LR following error dynamic model / Follow error dyn) — shows the following error that the dynamic model determines, i.e. the setpoint/actual difference this monitoring evaluates.
- p2546 (LR dynamic following error monitoring tolerance / s_delta_mon tol) — the tolerance the following error may reach; this message is raised as soon as r2563 exceeds it.
Acknowledging and restarting
As a fault, the message takes the drive out of operation and it must be acknowledged before the drive will restart; the acknowledgement is immediate. When the drive is configured to output the same condition as an alarm (A) instead, it triggers no automatic reaction and does not have to be acknowledged.
The same on every family
Every manual that describes F07452 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |

| G130, G150 | OFF1 (OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1556 |
| S120, S150 | OFF1 (OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2819 |

Questions technicians ask
What does fault F07452 mean on a SINAMICS drive?
The difference between the position setpoint and the position actual value — the following error shown in r2563 — is greater than the tolerance set in p2546. The drive raises this as a fault and can also output the same condition as an alarm.
What causes F07452 (LR: Following error too high)?
The manuals name an exceeded drive torque or accelerating capacity, a position measuring system fault, an interrupted encoder cable, an incorrect position control sense, locked mechanics, or excessively high traversing velocity or position setpoint differences.
How do I clear fault F07452?
Check and resolve the causes listed on this page, then acknowledge the message — the fault is acknowledged immediately. As an alarm it needs neither reaction nor acknowledgement.
Which parameters belong to F07452?
r2563 shows the following error that the dynamic model determines, and p2546 is the tolerance whose exceedance triggers the message.
