Load-free alignment EnDat-Encoder
While the EnDat encoder is being calibrated, the ZETADYN 4 energises the motor with direct current.
In the process, the rotor jumps to the centre of the nearest pole. In this rotor position, the offset value
is saved to the EnDat encoder and the EnDat encoder is subsequently set to position "0".
Information
The calibration should always be done twice. Any inaccuracy in the 1st calibration is detected by the
2nd calibration and can be corrected.
