Rotation
Direction is
reversed.
It cannot be
started or
positioning
completed
cannot be
output or
delayed.
Problem
The Servo Drive is set
to the opposite
rotation direction.
Reversed forward/
reverse direction pulse
output signals
(Origin Search)
Inconsistency
between the
parameter that sets
the origin proximity
sensor polarity and the
one that sets the origin
proximity input polarity
(in the PCU).
(Origin Search)
Wrong wiring of the
origin proximity input
The in-position width
of the Servo Drive is
narrow, and thus the
present position does
not enter the in-
position width.
(Because the current
operation does not
complete until the
present position
enters the in-position
width, you cannot start
the next position.)
Wrong wiring of the
positioning completed
of the Servo Drive
Servo Drive gain is
low.
Probable cause
CJ Position Control Units OPERATION MANUAL (CJ1W-NC214/234/414/434)
JOG the machine and if
the rotation direction of
the Servo Drive is
opposite the JOG
direction, the rotation
direction of the Servo
Drive is reversed. Also
check for reversed
feedback signals
(phases A and B) and
reverse rotation setting
of the parameter.
Check the wiring of the
forward/reverse
direction pulse output
signals.
Check the parameter
and sensor polarities
again.
Check if the origin
proximity input sensor in
the Operating area turns
ON/OFF.
Check if the positioning
completed in the
Operating area turns
ON/OFF.
Item to check
−
−
Set the rotation direction
of the Servo Drive
correctly.
Wire correctly.
Set the correct
parameters.
Wire the origin proximity
input correctly.
Widen the in-position
width of the Servo Drive.
Wire the positioning
completed correctly.
Adjust the Servo Drive
gain.
