Error 9521 · CNCelite 8058 / 8060 / 8065 / 8070
Message: Communication error at feedback. Wrong CRC.
Detection
On startup or normal operation of the system.
Cause
Rotary or linear encoder configuration has been lost. The CRC of the connected FAGOR absolute linear encoder has not been identified by the drive.
Solution
Check the connection of the encoder and the level of the signals provided by the feedback device. If "Current value = 1", feedback selected in SPEEDFBID; if "Current value = 2", feedback selected in POSITIONFBID.
