Cause : Fine encoder calibration activated comes when the phases of the fine encoder calibration using the alarm value. a process in which precise adjustments are made to the calibration settings of an encoder. Encoders are devices used to measure the position, speed, or direction of rotating shafts or linear motion. Calibration ensures that the encoder provides accurate and reliable measurements.

Alarm value (interpret decimal):
1: Fine encoder calibration active.
2: Rotating measurement started (set the setpoint speed > 40 % rated motor speed).
3: Rotating measurement lies within the speed and torque range.
4: Rotating measurement successful: pulse inhibit can be initiated to accept the values.
5: Fine encoder calibration is calculated.
10: Speed too low, rotating measurement interrupted.
12: Torque too high, rotating measurement interrupted.

Re alarm value = 10: Increase the speed.
Re alarm value = 12: Bring the drive into a no-load condition.
