Prevention
The wiring of the home input signal or
limit signal is incorrect.
Correct the wiring of the home input
signal or limit signal.
Check to see if any of the conditions
that are given as causes exist in
advance.
The home input sensor or limit sensor
is installed in the wrong location.
Correct the installation location of the
home input sensor or limit sensor so
that they do not turn ON at the same
time.
The contact logic of the home input
signal or limit signal is not correct.
Correct the contact logic (N.C./N.O.)
of the home input signal or limit sen-
sor.
The home input signal output device
or limit sensor failed.
Replace the home input signal output
device or limit sensor.

Prevention
The set value of the home input mask
distance when the operating mode of
the MC_Home instruction is set to
Proximity Reverse Turn/Home Input
Mask Distance
is insufficient to decel-
erate from the homing velocity to the
homing approach velocity.
Check the home input mask distance,
homing velocity, and homing
approach velocity. Change the set-
tings so that they provide sufficient
travel distance to decelerate based on
the operating specifications of the
MC_Home instruction.
Check the operating specifications for
the MC_Home instruction, then set
the home input mask distance, hom-
ing velocity, and homing approach
velocity so that they provide sufficient
travel distance to decelerate.
