Operating Mode 2 Connection Example

The origin search operation is completed at the first phase-Z signal after the
rising edge of the Origin Proximity Input Signal is detected, deceleration is
completed, and the falling edge of the Origin Proximity Input Signal is
detected.

Operating mode 2 is the same as operating mode 1 except that the servo
driver's Positioning Completed Signal (INP) is used as the origin search's
Positioning Completed Signal.
In this example, a servo driver is used and the encoder's phase-Z output is
used as the Origin Input Signal terminal. The servo driver is an OMRON
Servo Driver (W-series, U-series, or SMART STEP A-series.
Set the Servo Driver so that the Positioning Completed Signal is OFF when
the motor is operating and ON when the motor is stopped. The origin search
operation won't end if the Positioning Completed Signal is not connected cor-
rectly from the Servo Driver or is not set correctly.
