What it means
A05005 is the cooling unit's alarm telling you that the flow rate of the cooling medium has fallen below the alarm value. The drive takes no automatic reaction and the alarm requires no acknowledgement, so nothing trips or locks out — the message draws attention to the reduced coolant flow so it can be corrected before it worsens.
Why it appears
- The cooling unit signals that the flow rate of the cooling medium has fallen below the alarm value.
What to check
- Check the feedback signals and their parameter assignment (p0260 ... p0267).
- Check the coolant feed.
Parameters the manual names
- p0260 — Cooling unit starting time 1 / RKA start time 1: the first parameter of the range p0260 ... p0267 in which the manual says to check the cooling unit's feedback-signal parameter assignment when this alarm appears.
Acknowledging and restarting
No acknowledgement is required for this alarm, and the drive does not react to it automatically. Attend to the condition itself by checking the cooling unit's feedback signals and parameter assignment (p0260 ... p0267) and the coolant feed, as listed under the checks above.
The same on every family
Every manual that describes A05005 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does A05005 mean on a SINAMICS drive?
It is an alarm from the cooling unit reporting that the flow rate of the cooling medium has fallen below the alarm value. The drive takes no automatic reaction to it.
Does A05005 need to be acknowledged?
No. The alarm requires no acknowledgement; you clear the condition itself by checking the feedback-signal parameter assignment and the coolant feed.
Which parameters belong to A05005?
The manual points to the range p0260 ... p0267 for checking the cooling unit's feedback signals and parameter assignment. p0260 is the cooling unit starting time 1 / RKA start time 1.
