Prevention
The latch enabled range specification
is invalid.
If an invalid latch enabled range is
specified to the instruction, correct it.
Specify a correct latch enabled range
based on the relationship between
the motion and sensor position.
There is a problem with the wiring of
the interrupt signal.
Correct any problems with the wiring
for the interrupt signal for the instruc-
tion.
Make sure that the wiring of the inter-
rupt signal is correct.
The sensor that outputs the interrupt
signal has failed.
If neither of the two causes listed
above are applicable, the sensor that
outputs the interrupt signal has failed.
Replace the sensor that outputs the
interrupt signal for the instruction
where this error occurred.

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.
