What it means
A07569 (Enc identification active) reports that encoder identification is running and the drive is waiting for its result: with p0400 = 10100 the drive tries to identify the connected encoder automatically, and the encoder still has not been identified. Depending on the drive's configuration, the same condition can also be raised as fault F07569 instead of the alarm.
Automatic identification only works if the encoder itself supports it: on encoders with an EnDat interface, on encoders with an SSI interface, or on a motor with DRIVE-CLiQ.
Why it appears
- The drive is waiting for the result of encoder identification started with p0400 = 10100, and the encoder still has not been identified.
- The wrong encoder is installed, or no encoder is installed.
- The wrong encoder cable is connected, or no encoder cable is connected to the Sensor Module.
- The DRIVE-CLiQ component is not connected.
What to check
- Check the encoder and the encoder cable, and connect them if necessary.
- Check the DRIVE-CLiQ connection and establish it if necessary.
- For SSI encoders, carry out the operator actions that the Function Manual requires for identification.
- If the connected encoder cannot be identified at all — for example an encoder without an EnDat interface — do not rely on automatic identification and enter the correct encoder type in p0400.
Parameters the manual names
- p0400 (encoder type selection): identification runs with the value 10100; if the connected encoder cannot be identified automatically, enter its correct type here instead of 10100.
Acknowledging and restarting
As an alarm, A07569 requires no acknowledgment — it accompanies the waiting phase of encoder identification and clears once the encoder has been identified or the correct encoder type has been entered in p0400. If the drive's configuration issues the condition as fault F07569, no automatic stop is triggered; remedy the cause and then acknowledge immediately. Identification itself runs while p0400 = 10100.
The same on every family
Every manual that describes A07569 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2849 |
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1583 |

Questions technicians ask
What does alarm A07569 Enc identification active mean?
The drive is running or waiting for automatic encoder identification with p0400 = 10100 and the encoder has not yet been identified. It is issued as an alarm and, depending on the drive's configuration, also as fault F07569.
Which encoders can be identified automatically?
Only encoders that support identification: encoders with an EnDat interface, encoders with an SSI interface, and motors with DRIVE-CLiQ.
How do I clear A07569?
Check that the correct encoder and encoder cable are connected to the Sensor Module and that the DRIVE-CLiQ connection exists. For SSI encoders carry out the operator actions from the Function Manual; if the encoder cannot be identified, enter its correct type in p0400.
Does A07569 have to be acknowledged?
No — as an alarm it needs no acknowledgment. If the configuration raises the condition as fault F07569, it is acknowledged immediately once the cause has been fixed.
