What it means
F37001 is issued when the power unit of the HF Damping Module detects an overcurrent condition. The manual notes that the HF Choke Module is a reactor module, and names both the HF Choke Module and the HF Damping Module as the components to suspect. The stored fault value tells you which output phase was affected.
Why it appears
- The power unit has detected an overcurrent condition.
- The HF Choke Module or the HF Damping Module is defective.
- The resonance frequency of the output filter was excited.
What to check
- Check the HF Choke Module and the HF Damping Module and, if required, replace them.
- Reduce the motor power in the proximity of the fault-generating frequency.
Reading the message value
- The drive stores the fault cause in r0949 as a binary value, to be interpreted bitwise: each set bit names the phase on which the overcurrent was detected.
- Bit 0: Phase U.
- Bit 1: Phase V.
- Bit 2: Phase W.
Parameters the manual names
- r0949 — read the fault value of this fault here and interpret it bitwise in binary to see which phase (U, V or W) reported the overcurrent.
Acknowledging and restarting
The drive coasts down when this fault trips and will not restart until it has been acknowledged; the manual calls for immediate acknowledgement. Establish the cause first — check the HF Choke Module and the HF Damping Module, replace them if required — then acknowledge the fault and restart the drive.
The same on every family
Every manual that describes F37001 gives it the same reaction, acknowledgement and message class.

|---|---|---|---|---|---|
| S120, S150 | OFF2 | IMMEDIATELY | General drive fault (19) | None | SINAMICS S120, S150 List Manual · p. 3260 |

Questions technicians ask
What causes fault F37001 on SINAMICS?
The power unit of the HF Damping Module has detected an overcurrent. The possible causes are a defective HF Choke Module or HF Damping Module, or the resonance frequency of the output filter having been excited.
How do I clear F37001?
Check the HF Choke Module and the HF Damping Module and replace them if required, and reduce the motor power in the proximity of the fault-generating frequency. Then acknowledge the fault; the drive coasts down and will not start again until it is acknowledged.
Which phase does F37001 refer to?
The fault value in r0949 is interpreted bitwise: bit 0 stands for phase U, bit 1 for phase V and bit 2 for phase W.
