What it means
F08010 tells you that the analog-to-digital converter in the drive's control hardware has stopped delivering converted data. Where that converter sits depends on the family: on the G120 the message is titled "CU: Analog-to-digital converter" and the converter is on the Control Unit, while on the G130, G150, S120 and S150 it is titled "TB: Analog-digital converter" and the converter is on Terminal Board 30, which belongs to the Controller Extension (CX). The titles differ, but the cause and the remedy read the same. Depending on how the drive is configured, the same condition can also be output as an alarm (A) or entirely without a reaction (N).
Why it appears
- The analog-to-digital converter on the affected control hardware has not supplied any converted data; the manuals list this as the single cause and name no underlying fault behind it.
What to check
- Check the power supply — the manuals give this as the first step for every family.
- If the fault persists, replace the hardware: Terminal Board 30 on the G130, G150, S120 and S150, or the Control Unit on the G120.
Acknowledging and restarting
The fault must be acknowledged immediately, and acknowledgement only takes effect with a POWER ON — the affected unit has to be powered down and powered up again, so a reset from the operator panel while the drive stays powered does not clear it. When the condition is configured as an alarm (A) or without any reaction (N), the manual specifies no acknowledgement.
What differs between the drive families
Straight from the manuals' own fields — F08010 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Infeed: NONE (OFF1, OFF2) Servo: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2) Vector: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3, STOP2) Hla: NONE (OFF1, OFF2) | IMMEDIATELY (POWER ON) | Hardware/software error (1) | Controller Extension (CX) | SINAMICS S120, S150 List Manual · p. 2917 |
| G130, G150 | Vector: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3, STOP2) Infeed: NONE (OFF1, OFF2) | IMMEDIATELY (POWER ON) | Hardware/software error (1) | Controller Extension (CX) | SINAMICS G130, G150 List Manual · p. 1632 |
| G120 | OFF1 (IASC/DCBRK, NONE, OFF2, OFF3, STOP2) | IMMEDIATELY (POWER ON) | Hardware/software error (1) | — | SINAMICS G120 · p. 898 |
The drives this code lives on

Questions technicians ask
What does fault F08010 mean on a SINAMICS drive?
The analog-to-digital converter in the control hardware has not supplied any converted data. On the G120 it sits on the Control Unit; on the G130, G150, S120 and S150 it sits on Terminal Board 30 (Controller Extension).
How do I fix F08010?
The manual's remedy is to check the power supply first and then replace the hardware — Terminal Board 30 or the Control Unit, depending on which family the code appears on.
Why won't F08010 clear with a simple panel reset?
Acknowledgement only takes effect with a POWER ON, so the unit must be powered down and up again. A reset while the drive remains powered does not clear the fault.
Can F08010 appear as an alarm instead of a fault?
Yes — depending on the drive's configuration, the same condition can also be output as an alarm (A) or without any reaction (N).
