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

Stop (See note.)
Starts when ORG(889)
is executed.
Note: The Origin Input Signal can be detected immediately
after the Origin Proximity Input Signal goes from ON
to OFF if the deceleration time is short, e.g., starting
from within the Origin Proximity Input Signal.
