CHAPTER 4 PARAMETER
(4) Reference signal for shift operation homing profile (equivalent to homing profile 4 of FALDIC-α
Series)
Upon detection of a reference signal for shift operation after the start of homing, the motion
reverses to the point ahead of the reference signal for shift operation, and then the motion
continues at the creep speed for homing to detect the reference signal for shift operation and
determine the home position.
Accurate homing (highly reproducible zero position) is realized only with the reference signal for
shift operation without using the reference signal for homing (deceleration starting signal).

Because rotation reverses in the direction opposite to the OT direction upon OT detection to
detect the reference signal for homing (deceleration starting signal) and reference signal for shift
operation, homing can be secured. The reverse rotation after OT detection follows (2) OT
reference homing profile.
