What it means
A06400 — Infeed: Line supply data identification selected/active — is an alarm from the infeed that reports a status rather than a fault: the line supply data identification has been selected and is active. At the next pulse enable the drive measures the line inductance and the DC link capacitance. The alarm simply accompanies this measurement; it does not report a problem with the supply or the hardware.
Why it appears
- The line supply data identification has been selected and is active on the infeed.
- The measurement of the line inductance and of the DC link capacitance that this identification performs takes place at the next pulse enable.
What to check
- No remedy is necessary — the manual states this explicitly for the alarm.
- Leave the drive to run the measurement at the next pulse enable; once it has completed, the alarm withdraws itself.
Parameters the manual names
- p3410 (Infeed identification method / INF ID_type) — the parameter the manual cross-references in the cause of this alarm; the infeed identification method is set here, and the alarm is displayed while the line supply data identification selected with it is active.
Acknowledging and restarting
No acknowledgement is required. The alarm is withdrawn automatically once the measurement of the line inductance and the DC link capacitance has been completed — there is nothing to reset by hand.
The same on every family
Every manual that describes A06400 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does alarm A06400 mean on a SINAMICS infeed?
It means the line supply data identification is selected and active. At the next pulse enable the drive measures the line inductance and the DC link capacitance.
How do I clear or acknowledge A06400?
You do not have to do anything. The alarm is withdrawn automatically after the measurement has been completed, and the manual states that no remedy is necessary.
Which parameter is behind A06400?
p3410, the infeed identification method (INF ID_type). The manual cross-references it in the alarm's cause, because the alarm appears while the identification selected with it is active.
