 Typical homing profiles
(1) Basic homing profile (equivalent to homing profile 1 of FALDIC-
α
Series)
Described here is the homing profile of the most basic motion, in which homing is started, the
reference signal for homing (deceleration starting signal) is detected and deceleration to the creep
speed for homing occurs, and the reference signal for shift operation is detected and movement by
the home position shift unit amount is caused until the motion is stopped.
Use the profile if the machine stopping position is less than the reference signal for homing
(deceleration starting signal) or reference signal for shift operation.
Because nOT nor -OT is installed for homing of a rotating body as an indicator of the
traveling limit, this homing profile is used in principle.

To cancel homing upon detection of +OT or -OT, specify 1 (stop) to parameter PA2_24
(selection of operation at OT during homing).
