Load-free alignment EnDat-Encoder
When aligning the EnDat encoder, the frequency inverter supplies the motor with direct current. During
this, the rotor jumps to the middle of the nearest poles. In this rotor position, the offset value is stored
in the encoder, which sets the encoder to the
“
0
“
position.
Information
The calibration should always be done twice. Any inaccuracy in the 1st calibration is detected by the
2nd calibration and can be corrected.
