3-9-8 Homing function
• Two different homing function are available by setting homing mode selec-
tion (P068).
• When trigger signal of homing (70: ORG), the inverter starts homing oper-
ation. When homing is completed, current position data is reset (0).
• Direction of homing is specified in P069.
• If homing is not operated, position at power up is regarded as home posi-
tion (0).
(1) Low speed homing (P068 = 00)
