Note
The control may not always recognize the need for recalibration. If it detects such a need, it
sets MD34210 to 0 or 1. The following is detected: changeover to another gear speed with a
different gear ratio between the encoder and load.
In all other cases, the user must overwrite MD34210.
Data backup
When machine data is backed up, the status of MD34210 ENC_REFP_STATE is also saved.
By loading this data set, the axis is automatically deemed calibrated!
If the data set has been taken from another machine (e.g. series startup), calibration must
still be carried out after loading and activating the data.
