Description
Homing Ok is cleared at motor coast only while motor is running
and a new homing is needed. The option is a typical selection for
sensorless control with a mechanical brake holding the position
at stand still.
Homing Ok is only cleared at new start of the selected homing
function. The option is a typical selection for absolute encoders.
After completing the selected homing function Parameter 17-74
Position Offset is automatically set to the offset calculated by:
Parameter 17-74 Position Offset = (Parameter 17-82.0 Home
Position) - (Position value read from encoder). Start a new
homing to re-calculate Parameter 17-74 Position Offset, for
example, after replacing the encoder.
