Error message Meaning
Possible cause and
remedial action
Reference
CW limit switch active. This is a limit-sensor error.
The sequence program
stops (stops immediately
during pulse output).
• +LS input is turned on
while the motor is in
operation.
• Operation command has
been entered when +LS
input is on.
Perform mechanical home
seeking or a continuous
operation.
Mechanical home seeking
returns to the mechanical
home position.
Continuous operation starts
an operation in the
rotational direction opposite
to the stopped LS
regardless of the rotational
direction setting. The
operation stops when the
control escapes the LS.
Check if the output logic of
the LS used matches that of
the controller. ACTL
command
CCW limit switch
active. This is a limit-sensor error.
The sequence program
stops (stops immediately
during pulse output).
• -LS input is turned on
while the motor is in
operation.
• Operation command has
been entered when -LS
input is on.

CCW limit
switches active.
Limit-sensor input logic
setting error. +LS input and
-LS input both are turned
on at the same time.
The sequence program
stops (stops immediately
during pulse output). LS output logic for the
controller does not match
that of the LS being used.
Change the output logic for
the LS.
If this error message is
displayed when ±LS is at
contact B, check for
disconnection on the LS. ACTL
command
Driver alarm. An alarm from the driver.
The sequence program
stops (decelerates to a stop
during pulse output).
• The driver alarm input
turned on when the motor
was operating.
• An operation command
was input when the driver
alarm input was on.
• An anomaly has occurred
at the driver. Check the
operating condition of the
motor or ventilate and cool
the driver. Refer to the
operating manual for your
driver.
• If the driver is not in the
alarm state, check to see
if the alarm output logic of
the driver matches that of
the controller.
