Prevention
The Operation Selection at Negative
Limit Input or Operation Selection at
Positive Limit Input parameter is set to
No reverse turn
.
To prevent errors at the limit inputs,
set the Operation Selection at Nega-
tive Limit Input and Operation Selec-
tion at Positive Limit Input parameters
to
Reverse turn
.
Check to see if any of the conditions
that are given as causes exist in
advance.
The location of the homing input sig-
nal sensors, homing settings, and
homing start position cause a limit
input to be reached.
Correct the location of the input signal
sensors, homing settings, and homing
start position so that a limit input is
not reached.
The input signal sensor wiring is
incorrect or the sensor is faulty.
Correct the wiring of the input signal
sensor or replace the sensor.

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