Pr.1282 Home position return
setting method
Ignoring the home
4 (initial position (servo ON
value) position as the home
position)
Count type with front
6, 106, 206
end reference
*1 For EtherCAT communication, the value set in Index H6067 (Position window) is used.
*2 Change of the speed at which the proximity dog is detected may cause fluctuations of the average home position. Consider fluctuations of the
home position to set Pr.1283.

7. Position Control
7.4 Simple positioning function by point tables
The servo ON position is used as the home position. The settings of the direction for home position
return and home position shift distance are ignored.
Under Vector control: If the servo-lock function is enabled, output shutoff is canceled and the Position
control preparation ready (RDY) signal is turned ON after 0.1 second.
Position command speed
Point table selection signal, JOG
Under PM sensorless vector control: If the servo-lock function is enabled, the home position is set after
magnetic pole position detection.
Position command speed
Point table selection signal, JOG
The home position is determined based on the detection position of the front end of the proximity dog.
Deceleration starts at the front end of the proximity dog, and the position after the shift by the home
position shift distance is set as the home position.
Home position return direction
• Position pulse increasing direction: when Pr.1282 = "6" and the forward rotation command is given,
or when Pr.1282 = "106"
• Position pulse decreasing direction: when Pr.1282 = "6" and the reverse rotation command is given,
or when Pr.1282 = "206"
To input the X76 signal, set "76" in any parameter from Pr.178 to Pr.189 (Input terminal function
selection) to assign the function to a terminal.
Point table selection signal, JOG

HP1 (Home position return setting error) will be displayed in any of the following cases:
• The operation suddenly stops as the stroke end signal in the direction of travel is detected while the
position command is being created.
• After a position command is created, the Y36 signal remains OFF for 10 seconds.
