: encoder_offset_angle
The servo motors used have permanent magnets on the rotor. These generate a magnetic
field, whose orientation toward the stator depends on the rotor position. For electronic
commutation, the motor controller must always set the electromagnetic field of the stator
in the correct angle to this permanent magnet field. To do this, it constantly determines
the rotor position with an angle transmitter (resolver, etc.).
The orientation of the angle transmitter to the permanent magnetic field must be entered
in the object
encoder_offset_angle
. This angle can be determined with the
parameterisation software. The angle determined by the parameterisation software lies
around 180°. It must be calculated as follows:
encoder_offset_angle = "offset angle of the angle encoder"
