What it means
F30047 is raised when the cooling unit reports that the cooling medium is flowing more slowly than the fault threshold allows. The drive coasts down and does not start again until the fault has been acknowledged.
Why it appears
- The cooling medium flow rate is lower than the set fault threshold.
What to check
- Check the cooling unit's feedback signals and their assignment in the parameter range p0260 ... p0267.
- Check that coolant is actually being fed to the cooling unit.
- Verify the coolant's thermal conductivity.
- Verify the coolant concentration as well.
Parameters the manual names
- p0260 — Cooling unit starting time 1 / RKA start time 1: the first parameter of the p0260 ... p0267 range whose assignment to the cooling unit feedback signals has to be checked for this fault.
Acknowledging and restarting
The drive coasts down and must be acknowledged before it will start again. This fault can be acknowledged immediately.
The same on every family
Every manual that describes F30047 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does fault F30047 mean on a SINAMICS drive?
It means the cooling unit's cooling medium flow rate has dropped below the set fault threshold, so the drive coasts down and stops.
Which parameters are checked for F30047?
The manual points to the parameter range p0260 ... p0267, which holds the cooling unit feedback signal assignments; p0260 is the cooling unit starting time 1 (RKA start time 1).
How can I clear F30047 and restart the drive?
Work through the checks — feedback signal assignment, coolant feed, thermal conductivity and coolant concentration — then acknowledge the fault, which can be done immediately.
Why does the drive report the cooling medium flow rate as too low?
The cooling unit's flow monitoring has seen the flow fall under the fault threshold, which points to the coolant feed, its concentration or its thermal conductivity.
