Description of I/O Signals
2
Homing [ORG]: Sequence input signal (Reference value 5)
Homing position LS [LS]: Sequence input signal (Reference value 6)
Interrupt input: Sequence input signal (Reference value 49)
A homing motion is executed and the home position is determined.
This signal is enabled only when parameter PA1_01 (control mode selection) is set to "6"
(extension mode) or "7" (positioning function).
 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 at a speed of PA2_06.
(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.
