)
 A moving part is brought into contact with the machine end stopper to determine the home position.
 Home position return is performed in the following procedure.
1) Input the forward rotation signal (STF signal) or reverse rotation signal (STR signal) without selecting a point table or
JOG operation to perform the operation according to
Pr.453 High speed during home position return
.
2) When the moving part touches the machine end and a torque set by Pr.533 Home position return stopper torque or larger
is applied, the OL signal is output.
3) The condition is kept for 500 ms to establish stable press up condition.
4) After the condition (OL signal output condition) further lasted for
Pr.534 Home position return stopper duration
, this
position is determined as the machine end.
5) The home position is calculated by shifting the machine end position in the reverse direction by the home position shift
distance ( Pr.508 + Pr.509 ) at Pr.455 Home position return shifting speed .
 In any of the following cases, the home position return setting error (HP1) is displayed.
 Even after the shift from the power-ON position by 99999999 or -99999999 at the speed of Pr.453 High speed during home
position return , the contact condition cannot be achieved.
 The contact condition does not last for Pr.534 Home position return stopper duration .
 In 10 s after the shift by the home position shift distance, the in-position signal (Y36) is not turned ON.
