What it means
A07504 is raised when a motor data set (MDS) of the drive object has not been assigned to a drive data set. The drive expects every existing motor data set to be assigned in the drive data sets via the MDS number p0186[0...n], and it requires at least as many drive data sets as there are motor data sets. The alarm value tells you which motor data set is missing its assignment, so the condition can be corrected directly in the parameterization.
Why it appears
- A motor data set exists that is not assigned to the drive object.
- Not every existing motor data set is entered with its MDS number (p0186[0...n]) in the drive data sets.
- There are fewer drive data sets than motor data sets: the drive requires at least as many drive data sets as motor data sets.
What to check
- In the drive data sets, assign the motor data set that has not been assigned by entering its MDS number in p0186[0...n].
- Check whether all of the motor data sets are assigned to drive data sets.
- Delete any superfluous motor data sets, if such exist.
- If required, set up new drive data sets and assign them to the corresponding motor data sets.
Reading the message value
- The drive puts the number of the motor data set that has not been assigned into the message value.
- Read the alarm value in r2124 and interpret it as a decimal number — it is the number of the unassigned motor data set.
Parameters the manual names
- p0186 (Motor Data Sets (MDS) number): enter here, per drive data set, the MDS number that this drive data set uses — this is how the missing assignment of the motor data set is made.
- r2124 (Alarm value): holds the number of the motor data set that has not been assigned; read it for this alarm as a decimal number.
What differs between the drive families
Straight from the manuals' own fields — A07504 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | — | — | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2833 |
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1570 |

Questions technicians ask
What does alarm A07504 in SINAMICS mean?
It means a motor data set (MDS) exists that is not assigned to any drive data set. Every motor data set must be entered with its MDS number in p0186[0...n] of the drive data sets, and there must be at least as many drive data sets as motor data sets.
Which motor data set triggers A07504?
The alarm value names it: read r2124 and interpret the value as a decimal number — it is the number of the motor data set that has not been assigned.
How do I clear A07504?
Assign the unassigned motor data set in the drive data sets via p0186[0...n]. Then check that all motor data sets are assigned, delete superfluous motor data sets, or set up new drive data sets and assign them to the corresponding motor data sets.
Why does the alarm talk about drive data sets?
Because the assignment runs over the drive data sets: each drive data set must be given a motor data set via p0186[0...n], and the drive requires at least as many drive data sets as motor data sets. If you have more motor data sets than drive data sets, set up new drive data sets or delete the superfluous motor data sets.
