HOME sequence
error. Mechanical home seeking
did not proceed as planned.
The sequence program
stops (decelerates to a stop
during pulse output).
• +LS input, -LS input and
HOMELS input are all
turned on at the same
time.
• HOMELS input did not turn
on in a 3-sensor home
detection.
• -LS or +LS has been
detected while operating in
the CW or CCW direction,
respectively.
• The positions of +LS and
-LS are too close to the
position of HOMELS.
Separate HOMELS from
±LS so that ±LS and
HOMELS do not turn on at
the same time.
• Check the connection
between the controller and
±LS/HOMELS. If the
connection is correct:
Confirm that the detection
range of HOMELS is at
least 10 ms. If the
connection is incorrect:
Connect HOMELS. When
HOMELS is not used:
Select the 2-sensor mode.
If the shielding plate is
longer than the distance
between HOME LS and
+LS or between HOME LS
and -LS, reverse the
starting direction of home
detection.
SEN
command
Interpolation error. During the execution of
2-axis linear interpolation
operation, the speed of the
sub-axis, calculated from the
main axis, exceeded the
setting range. Correct the starting speed,
operating speed or
acceleration/deceleration
rate.
Invalid value. Invalid setting value error.
The sequence program
stops (decelerates to a stop
during pulse output).
• A value outside the setting
range has been set.
• The number of fractional
digits differed between the
unit value and movement
amount.
Enter the correct value.
