What it means
F07502 «Drive: Encoder Data Set EDS not configured» is raised when a drive data set has no encoder data set assigned to it: the number of the encoder data set belonging to that drive data set was never entered. The manual limits this fault to power units. The message value names the drive data set concerned (Drive data set: %1
). All manuals that describe this fault describe it identically, so one description covers every family on this page.
Why it appears
- The encoder data set belonging to the drive data set was not configured — no encoder data set number was entered into the associated drive data set.
- The fault is only raised for power units.
What to check
- Read the drive data set number from the message value and from the fault value in r0949.
- Enter the index of the encoder data set associated with that drive data set into p0187 (1st encoder).
- Enter the associated encoder data set index into p0188 (2nd encoder) and p0189 (3rd encoder) as well.
Reading the message value
- Message value:
Drive data set: %1
— the number shown identifies the drive data set in which the encoder data set entry is missing. - The fault value is stored in r0949 and is interpreted in decimal.
- The fault value contains the drive data set number of p0187, p0188 and p0189.
- The fault value is increased by 100 * encoder number.
- Example from the manual: for p0189 the fault value reads 3xx, where xx is the data set number.
Parameters the manual names
- r0949 — read the fault value here (decimal): it gives the affected drive data set number and, through the 100 * encoder number offset, shows which encoder entry is incomplete.
- p0187 — enter the index of the encoder data set belonging to the drive data set for the 1st encoder.
- p0188 — enter the associated encoder data set index for the 2nd encoder.
- p0189 — enter the associated encoder data set index for the 3rd encoder; with this encoder the fault value reads 3xx (xx = data set number).
Acknowledging and restarting
The drive coasts down when this fault occurs and must be acknowledged immediately before it can run again. Enter the missing encoder data set number in p0187, p0188 and p0189 first; the drive can only restart once the parameterization is complete and the fault has been acknowledged.
The same on every family
Every manual that describes F07502 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |

| S120, S150 | OFF2 | IMMEDIATELY | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2833 |

Questions technicians ask
What does fault F07502 mean on a SINAMICS drive?
A drive data set references an encoder data set (EDS) that was not configured: no encoder data set number was entered into the drive data set. The fault is only raised for power units.
How do I fix fault F07502?
Enter the index of the encoder data set associated with the affected drive data set into p0187 (1st encoder), p0188 (2nd encoder) and p0189 (3rd encoder), then acknowledge the fault.
How is the F07502 fault value decoded?
Interpret r0949 in decimal: it contains the drive data set number of p0187, p0188 and p0189, increased by 100 * encoder number — for p0189 the fault value reads 3xx, where xx is the data set number.
