F07569 fault in siemens 6RA80 DC Drive indicate that the Encoder identification active. This means during encoder identification (waiting) with p0400 = 10100, the encoder could still not be identified.

Either the wrong encoder has been installed or no encoder has been installed, the wrong encoder cable has been connected or no encoder cable has been connected to the Sensor Module, or the DRIVE-CLiQ component has not been connected.

1. check and, if necessary, connect the encoder / encoder cable.
2. check and, if necessary, establish the DRIVE-CLiQ connection.
3. for SSI encoders, carry out the required operator actions (see the Function Manual).
4. in the case of encoders that cannot be identified (e.g. encoders without EnDat interface), enter the correct encoder type in p0400.
