F05061 — Infeed VSM count

F05061 ("Infeed VSM count") is raised when the number of active Voltage Sensing Modules (VSM) assigned to the drive object of an infeed with chassis power units is not correct. The component named for this fault is the Voltage Sensing Module (VSM). The fault value in r0949 shows how many VSMs the drive currently has assigned to the drive object, so the count can be compared directly with the actual configuration.

• The number of active Voltage Sensing Modules (VSM) for the drive object infeed with chassis power units is not correct.
• For an A_Infeed, each active power unit must be assigned an active VSM — this also applies in a parallel circuit configuration.
• For an S_Infeed, the active drive object must be assigned at least one active VSM.

1. Read the fault value in r0949, interpreting it as a decimal number: it is the number of VSMs currently assigned to the drive object.
2. Compare this count with the required assignment — for an A_Infeed, an active VSM for each active power unit (also in a parallel circuit configuration); for an S_Infeed, at least one active VSM on the active drive object.
3. Adapt the number of active Voltage Sensing Modules (VSM) so that the assignment matches.

• The message value is shown as %1; the same fault value is stored in r0949 and is to be interpreted as a decimal number.
• Value: the number of VSMs that are currently assigned to the drive object. The manuals print no bit decoding for this value.

• r0949 — fault value: read it as a decimal number to see how many VSMs are currently assigned to the drive object.

There is no separate reset sequence: adapt the number of active VSMs first, then acknowledge the fault — the acknowledgment takes effect immediately. No further restart steps are described for this fault.
