What it means
A37310 (manual title: HF Choke Module: Overtemperature) signals that the temperature of the HF Choke Module heat sink has exceeded the permissible limit value; the manual also calls this module a reactor module. The code is described for SINAMICS S120 and S150, and depending on the drive configuration the same condition can also be output as a fault (F37310).
Why it appears
- Cooling is insufficient, for example because a fan has failed.
- The HF Choke Module is overloaded.
- The ambient temperature is too high.
What to check
- Check whether the fan is running.
- Check the fan elements.
- Check whether the ambient temperature is within the permissible range.
Reading the message value
- The drive enters the alarm value into r2124. Interpret it as a decimal number: it contains the heat sink temperature in units of 0.01 °C.
Parameters the manual names
- r2124 (alarm value) — read out here the temperature at which the drive raised A37310; interpret the value as decimal in units of 0.01 °C.
Acknowledging and restarting
If the drive outputs the condition as a fault (F37310), it performs none of the OFF1, OFF2 or OFF3 reactions, and the fault is to be acknowledged IMMEDIATELY. The manual states: This fault can only be acknowledged after the alarm threshold for alarm A05000 has been undershot.
So remove the cause, let the heat sink cool until its temperature lies below the A05000 alarm threshold, then acknowledge the fault and restart the drive.
The same on every family
Every manual that describes A37310 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Power electronics faulted (5) | None | SINAMICS S120, S150 List Manual · p. 3267 |

Questions technicians ask
What does alarm A37310 mean on a SINAMICS S120 or S150?
It reports that the heat sink of the HF Choke Module (reactor module) has exceeded its permissible temperature limit value. Depending on the configuration, the same condition can also appear as fault F37310.
What causes A37310?
The manuals list insufficient cooling or fan failure, an overload of the module, and an ambient temperature that is too high.
How do I clear fault F37310?
The fault can only be acknowledged once the heat sink temperature has dropped back below the alarm threshold for A05000. Acknowledge it IMMEDIATELY once that is the case, and restart the drive.
Where can I read the temperature belonging to A37310?
In the alarm value r2124; interpret it as a decimal number in units of 0.01 °C.
