What it means
F49152 is raised when the feedback signal confirming the ON command of the cooling unit is missing. The drive issues the ON command to the cooling unit and waits for the feedback signal; if it does not arrive within the starting time set in p0260, the drive trips. The same fault is raised if the feedback was present at switch-on but fails while the cooling unit is running.
Why it appears
- After the ON command was issued, the feedback signal was not received within the starting time selected in p0260.
- The feedback signal failed in operation.
- The cooling unit was stopped by an external signal.
What to check
- Check the wiring between the cooling unit and the input terminal (Terminal Module).
- Check the wiring between the output terminal (Terminal Module) and the cooling unit.
- Check the external control device for the cooling unit.
Parameters the manual names
- p0260 (Cooling unit starting time 1, RKA start time 1) — the window after the ON command in which the cooling unit feedback must arrive; if the feedback is not received within this time, the drive raises F49152.
Acknowledging and restarting
On this fault the drive coasts down (OFF2) and the fault must be acknowledged immediately — the drive will not start again until it has been acknowledged. Eliminate the cause first, then acknowledge the fault and restart the drive.
The same on every family
Every manual that describes F49152 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does fault F49152 mean on a SINAMICS drive?
The drive switched its cooling unit on, but the feedback signal confirming the ON command is missing. Either the feedback did not arrive within the starting time set in p0260, or it failed while the cooling unit was running.
Which parameter belongs to F49152?
p0260, the cooling unit starting time (RKA start time 1). If the ON command feedback is not received within this time, the drive raises F49152.
How do I fix fault F49152?
Check the wiring between the cooling unit and the input and output terminals of the Terminal Module, and check the external control device for the cooling unit. Then acknowledge the fault immediately and restart the drive.
Why did my drive trip F49152 even though the cooling unit was working before?
The fault also comes when the feedback signal fails in operation, or when the cooling unit was stopped by an external signal.
