Homing function
- Two different homing functions are available by setting homing mode selection ().
- When trigger signal of homing (: ORG), the inverter starts homing operation. When
homing is completed, current position data is reset (0).
- Direction of homing is specified in .
- If homing is not operated, position at power up is regarded as home position (0).
