What it means
A07089 appears when a function module is to be activated although the units have already been changed over. Because a function module may no longer be activated after such a changeover, the drive blocks the activation and reports it as this alarm.
Why it appears
- A function module activation was attempted.
- The units had already been changed over at that moment; from that point on, activating a function module is not permissible.
What to check
- Apply the remedy the manual gives:
Restore units that have been changed over to the factory setting.
- The unit system is defined by the parameters the manual cross-references for this alarm: p0100 and p0505 are named for every family covered here, p0349 only in the G130, G150, S120 and S150 descriptions.
Parameters the manual names
- p0100 — IEC/NEMA mot stds: the motor standard setting (IEC or NEMA) that belongs to the unit changeover this alarm refers to.
- p0505 — Unit sys select / Selecting the system of units: selects the drive's unit system, the very setting the remedy returns to the factory state.
- p0349 — Unit_sys mot ESB / System of units motor equivalent circuit diagram data: carries the unit system of the motor equivalent circuit diagram data; named for this alarm in the G130, G150, S120 and S150 descriptions.
Acknowledging and restarting
No acknowledgement is required for this alarm. The fix the manual describes is not a reset but returning the changed-over units to the factory setting.
What differs between the drive families
Straight from the manuals' own fields — A07089 is not described identically everywhere.

Questions technicians ask
What does alarm A07089 mean in SINAMICS?
It means a function module activation was attempted after the units had already been changed over. Since activation is not permissible in that state, the drive blocks it.
How do I fix A07089?
Restore the units that have been changed over to the factory setting. The unit-system parameters behind the alarm are p0100 and p0505, plus p0349 on the G130, G150, S120 and S150.
Does A07089 have to be acknowledged?
No, no acknowledgement is required. The remedy is returning the changed-over units to the factory setting, not a reset.
Which parameters belong to alarm A07089?
p0100 (IEC/NEMA mot stds) and p0505 (Selecting the system of units) in all descriptions, plus p0349 (System of units motor equivalent circuit diagram data) in the G130, G150, S120 and S150 descriptions.
