•
There was no home signal input
during the homing operation.
•
A limit signal was detected before
there was a home input.
Check the home input settings and
wiring and correct them so that the
home signal is input during homing
based on the operation specifications
of the MC_Home instruction. Also, set
the system so that the home signal is
detected before the limit signals.
Set the system so that the home sig-
nal is input during the homing opera-
tion. Make sure that the home signal
is detected before a limit signal. Also
check to make sure there are no wir-
ing problems with the home input.

There was no home proximity signal
input during the homing operation
when a home proximity input signal
was specified.
Check the home proximity input set-
tings and wiring and correct them so
that the home proximity signal is input
during homing based on the operation
specifications of the MC_Home
instruction.
Set the system so that the home prox-
imity signal is input during the homing
operation. Also check to make sure
there are no wiring problems with the
home proximity input.
