What it means
A08800 is raised while the PROFIenergy energy-saving mode is active. The alarm signals the drive's current operating condition: it is in this energy-saving mode and reports the ID of the active mode as its alarm value. The drive takes no automatic reaction to the alarm — it simply accompanies the mode until the mode is exited.
Why it appears
- The PROFIenergy energy-saving mode is active. This is the only cause the manuals give: the alarm appears because the mode is in effect and is withdrawn again when the mode is exited.
What to check
Nothing needs to be repaired or reparameterized at the converter — the alarm is withdrawn automatically when the energy-saving mode is exited. The manuals list the events after which the mode is exited:
- The higher-level control sends the PROFIenergy command end_pause.
- The higher-level control has changed into the STOP operating state.
- The PROFINET connection to the higher-level control has been disconnected.
Reading the message value
- The alarm value is stored in r2124 and is interpreted as a decimal number. It contains the mode ID of the active PROFIenergy energy-saving mode.
- For the mode ID the manuals also reference r5600 (Pe energy-saving mode ID).
Parameters the manual names
- r2124 — alarm value: read the mode ID of the active PROFIenergy energy-saving mode from it; for this alarm the value is interpreted as a decimal number.
- r5600 — Pe energy-saving mode ID: shows the ID of the PROFIenergy energy-saving mode, referenced by the manuals for this alarm.
Acknowledging and restarting
No acknowledgment is required. The alarm is automatically withdrawn when the energy-saving mode is exited — after the PROFIenergy command end_pause is received from the higher-level control, after the higher-level control has changed into the STOP operating state, or when the PROFINET connection to the higher-level control has been disconnected.
What differs between the drive families
Straight from the manuals' own fields — A08800 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Communication error to the higher-level control system (9) | None | SINAMICS S120, S150 List Manual · p. 2930 |
| G130, G150 | NONE | NONE | Communication error to the higher-level control system (9) | None | SINAMICS G130, G150 List Manual · p. 1644 |
| G120 | NONE | NONE | Communication error to the higher-level control system (9) | — | SINAMICS G120 · p. 902 |
The drives this code lives on

Questions technicians ask
What does alarm A08800 mean on a SINAMICS drive?
It means the PROFIenergy energy-saving mode is active. The drive keeps the alarm in place until this mode is exited and reports the active mode's ID as the alarm value.
How do I reset or acknowledge A08800?
No acknowledgment is needed. The alarm is withdrawn automatically as soon as the energy-saving mode is exited.
How does the drive leave the PROFIenergy energy-saving mode?
The mode is exited when the higher-level control sends the PROFIenergy command end_pause, when the higher-level control changes into the STOP operating state, or when the PROFINET connection to the higher-level control is disconnected.
Where can I see which PROFIenergy mode is active?
The alarm value in r2124 contains the mode ID of the active mode and is interpreted as a decimal number. r5600 additionally shows the Pe energy-saving mode ID.
