 Home position return function selection (Pr.1095), Home position return
position data (Pr.1096, Pr.1097)
• Use Pr.1095 Home position return function selection to select whether to use a positive or negative value for the
position data for home position return (Pr.1096 and Pr.1097).
Pr.1095 setting
9999 (initial value)
1000
• Position data for home position return
Set the final position for the home position return. Set the upper 4-digit data in Pr.1097 and the lower 4-digit data in
Pr.1096.
Position command (before electronic gear) = Position data for home position return (Pr.1096 and Pr.1097)
Current position (before electronic gear) = Position data for home position return - Droop pulse (converted before electronic
gear)
The droop pulses are not cleared.
NOTE
• If parameters are copied from an inverter without functions of Pr.1096 and Pr.1097 to a new inverter, "----" is displayed for the
settings of Pr.1096 and Pr.1097 on the operation panel. The operation for the setting of "0 (initial value)" is performed. (Refer

 Home position return error
• If home position return is not normally completed, the following warnings appear on the operation panel.
Operation panel
indication
HP1 Home position return setting error
HP2 Home position return uncompleted
• Unless the home position return is completed (the ZP signal is turned ON), position control cannot be performed (except
when JOG operation during position control or the roll feed mode is enabled).
• The Home position return failure (ZA) signal is output while the home position return warning is activated. To use the ZA
signal, set "56" (positive logic) or "156" (negative logic) in any parameter from Pr.190 to Pr.197 (Output terminal function
selection) to assign the function.
 Sudden stop (Pr.464, Pr.1292, and X87 signal)
• When the Sudden stop (X87) signal is assigned to an input terminal, turning ON the X87 signal (normally open input) stops
the operation according to the deceleration time slope set by Pr.464 Digital position control sudden stop deceleration
time. (For EtherCAT communication, the value set in Index H6085 (Quick stop deceleration) can be also used.) When the
deceleration time set in Pr.464 is longer than that set by the current position control command, the deceleration time slope
set by the current position control command is applied. After the operation is stopped, turning OFF the X87 signal (normally
open input) starts position control again. To input the X87 signal, set "87" in any parameter from Pr.178 to Pr.189 (Input
terminal function selection) to assign the function to a terminal.
• When the ones place of the set value in Pr.1292 Position control terminal input selection is "0", the normally open input
is applied and the operation is stopped by turning ON the X87 signal. When the ones place is "1", the normally closed input
is applied and the operation is stopped by turning OFF the X87 signal.
