F06320Master/slave: 4-channel multiplexer control not valid

What it means

The drive routes the active current setpoint for master/slave operation through a 4-channel multiplexer. Connector input p3572 selects which of the four channels is used; only the values 0, 1, 2 and 3 are valid. The drive has identified a value outside this set at this input. Operation is not interrupted: the multiplexer control remains effective with the previous value until a valid value is present again.

Why it appears

  • Connector input p3572, which selects the channel of the 4-channel multiplexer for the master/slave active current setpoint, was given a value other than 0, 1, 2 or 3.
  • The invalid value originates from the signal source of the BICO interconnection to p3572.

What to check

  1. Check the interconnection used to control the multiplexer (CI: p3572).
  2. Check the signal value that the signal source of this BICO interconnection delivers.

Reading the message value

  • The message value corresponds to the fault value in r0949 and is to be interpreted as a decimal number.
  • It contains the invalid value with which the multiplexer was to be controlled; the values 0, 1, 2 and 3 would have been valid.

Parameters the manual names

  • p3572 — CI: Master/slave active current setpoint multiplexer selection: the connector input whose interconnection selects the multiplexer channel and must be checked for this fault.
  • r0949 — Fault value: read here, interpreted as a decimal number, which invalid value was present at the multiplexer selection.

Acknowledging and restarting

The fault can be acknowledged immediately — no waiting time applies. Because the drive does not trip, no restart of the converter is required; once the interconnection to p3572 again supplies one of the valid values 0, 1, 2 or 3, acknowledging clears the message.

The same on every family

Every manual that describes F06320 gives it the same reaction, acknowledgement and message class.

Questions technicians ask

What does SINAMICS fault F06320 mean?

The drive has detected an invalid value at connector input p3572, which controls the 4-channel multiplexer for the master/slave active current setpoint. Only the values 0, 1, 2 and 3 are valid selections.

How do I fix fault F06320?

Check the interconnection to control the multiplexer (CI: p3572) and the signal value delivered by the signal source of that BICO interconnection. Once a valid value is present again, the fault can be acknowledged immediately.

Does F06320 stop the drive?

No. The fault is signalled but the drive does not trip — the multiplexer control remains effective with the previous value.

Where can I see which value triggered F06320?

In the fault value r0949, interpreted as a decimal number. It contains the invalid value that was applied to the multiplexer control.
