CJ Position Control Units OPERATION MANUAL (CJ1W-NC214/234/414/434)
The feedback present position
became greater than the
upper limit (overflow) or
smaller than the lower limit
(underflow) of the usable
range when the Position and
Speed error Monitor function
was enabled.
When you use an absolute
encoder, absolute data could
not be read properly upon
servo lock.
When you use an absolute
encoder, invalid absolute data
was read upon servo lock.
When you use an absolute
encoder, the present position
became greater than the
upper limit (overflow) or
smaller than the lower limit
(underflow) of the usable
range due to the absolute data
which was read upon servo
lock.
The command present
position became greater than
the upper limit (overflow) or
smaller than the lower limit
(underflow) of the usable
range during inching.
The MPG ratio setting is
outside the specified range.
Origin search operation was
stopped due to detection of a
limit input in the direction
opposite the origin input
detection direction.
Origin search operation was
stopped due to detection of a
limit input in the origin input
detection direction.
Origin search cannot be
continued because the limit
inputs in both directions were
detected.
Cause
Execute an error reset, and
then resolve the overflow/
underflow state by feedback
present position preset
(IOWR).
If this error occurs, the PCU
decelerates the applicable
axis to a stop.
Execute an error reset and
then lock the servo. If this
error occurs again, check the
connection of the encoder
pulse input with the Servo
Drive.
Execute an error reset and
then set up the absolute
encoder again and perform
origin positioning of PCU.
Remove the cause of the
command present position
overflow/underflow, check the
inching width, and then
execute an error reset.
If this error occurs, the PCU
decelerates the applicable
axis to a stop.
Check the setting of the MPG
ratio and then execute an
error reset.
If this error occurs, the PCU
decelerates the applicable
axis to a stop.
Check the input signal for
origin search and origin
search setting, and then
execute an error reset.
If this error occurs, the PCU
stops the applicable axis or
decelerates to a stop
according to the setting of the
corresponding axis
parameter.
