(3) At-start reverse rotation homing profile1 (equivalent to homing profile 3 of FALDIC- α Series)
After homing is started, a travel occurs in the direction opposite to the starting direction for homing
by the specified reverse traveling unit amount for homing while the reference signal for homing
(deceleration starting signal) is searched for.
This profiles used if the machine stopping position is larger than the reference signal for homing
(deceleration starting signal) or reference signal for shift operation.


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, secure homing is realized. The reverse rotation after OT detection follows (2) OT
reference homing profile.
