What it means
The drive shows Encoder 3: Reference point coordinate not in the permissible range when the reference point coordinate that arrives during encoder adjustment via connector input CI:p2599 lies outside half of the encoder range. Because the value is out of range, the drive cannot set it as the actual axis position. Depending on the drive configuration, the same condition can also be output as fault F07559.
Why it appears
- The reference point coordinate received when adjusting the encoder via connector input CI:p2599 lies outside half of the encoder range, so it cannot be set as the actual axis position.
- The maximum permissible value for the coordinate is displayed in the supplementary information of the message.
What to check
- Open the supplementary information of the message: it displays the maximum permissible value for the reference point coordinate.
- Set the reference point coordinate to a value less than the value from the supplementary information. The coordinate is p2599, received via CI:p2599; the manual also points to p2598, the signal source for this coordinate.
Parameters the manual names
- p2599 (CO: EPOS reference point coordinate value) — the reference point coordinate the drive receives via CI:p2599 during encoder adjustment; set it below the maximum value shown in the supplementary information.
- p2598 (CI: EPOS reference point coordinate signal source) — selects the signal source that supplies the reference point coordinate to CI:p2599; the manual refers to it when the received coordinate is out of range.
Acknowledging and restarting
As an alarm, A07559 triggers no automatic reaction and requires no acknowledgement. If the drive is configured to output the condition as fault F07559 instead, the drive reacts with OFF1 (OFF2 or OFF3 as the alternatives) and the fault must be acknowledged IMMEDIATELY.
The same on every family
Every manual that describes A07559 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2845 |
| G130, G150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1580 |

Questions technicians ask
What does A07559 mean on a SINAMICS drive?
It stands for 'Encoder 3: Reference point coordinate not in the permissible range': the coordinate received via connector input CI:p2599 during encoder adjustment lies outside half of the encoder range and cannot be set as the actual axis position.
How do I fix A07559?
Read the maximum permissible value from the supplementary information of the message and set the reference point coordinate to a value below it. The coordinate is supplied via CI:p2599, with p2598 as its signal source.
Does A07559 have to be acknowledged?
As an alarm, no: the drive takes no automatic reaction and no acknowledgement is needed. When the condition is output as fault F07559, the drive reacts with OFF1 (OFF2 or OFF3 as alternatives) and the fault must be acknowledged IMMEDIATELY.
Which parameter sets the Encoder 3 reference point coordinate?
p2599 (CO: EPOS reference point coordinate value) is the coordinate itself; p2598 (CI: EPOS reference point coordinate signal source) selects where it comes from.
