Operating Mode 1 without Origin Proximity Input Signal Reverse (Origin
Detection Method Setting = 1)
Depending on the length of the deceleration time, the stopping position may
change when the Origin Input Signal is detected during deceleration.
Operating Mode 2 (with Error Counter Reset Output, with Positioning
Completed Input)
This operating mode is the same as mode 1, except the Positioning Com-
pleted Signal (INP) from the Servo Driver is used. With origin search 0, the
Positioning Completed Signal from the Servo Driver connects to IN4. With ori-
gin search 1, it connects to IN5.
If origin compensation is not being applied, the Positioning Completed Signal
is checked after the Error Counter Reset Output. If origin compensation is
