CHAPTER 2 WIRING
Homing [ORG]: Sequence input signal (Reference value 5)
Homing position LS [LS]: Sequence input signal (Reference value 6)
A homing motion is executed and the home position is determined.
These functions are enabled only if the extension mode (parameter PA1_01= 6) and the positioning
2
operation (parameter PA1_01=7) are selected.
Function
The rising edge of the homing signal starts a homing motion. The homing motion follows the
settings of PA2_06 through PA2_18. If parameters are factory shipment settings, the following
motion is executed.

(1) After checking that the in-position signal is turned on, turn on the homing command.
(2) Once the in-position signal is turned off, you can turn off the homing command.
The motor rotates in the direction of PA2_10 (homing direction after reference signal detection) at a
speed of PA2_06 (homing speed).
(3) When the home position LS signal is turned on, the speed changes to creep speed for homing
(PA2_07).
(4) The motor moves the home position shift unit amount (PA2_14) from the first Z-phase after the
rising (or trailing) edge of the home position LS, and then it is stopped.
(5) The in-position signal is turned on with the stopping position being home position after homing
completion PA2_16. In addition, the homing completion signal is turned on.
