ON The PLC READY signal is turned from OFF
to ON when BUSY signal is turned ON.
Start is requested when start is not
possible in the axis operation state.
The set series of the servo parameter
"[Pr.100] Servo series" and the series of
connected servo amplifier are mismatch.
A servo amplifier/driver which is not
supported is connected.
The calculation process time of the
positioning etc. exceeds the operation
cycle.
• When the OPR retry invalid is set, the
near-point dog method machine OPR is
started with the OPR complete flag turned
ON.
• Scale origin signal detection method
machine OPR is started with the OPR
complete flag turned ON and the near-
point dog signal turned ON.
The near-point dog signal is turned OFF
during the deceleration from an OPR
speed to a creep speed by the near-point
dog method machine OPR.
In the count method 1) and 2) machine
OPR, a parameter "Setting for the
movement amount after near-point dog
ON" is smaller than a distance necessary
for deceleration stop from an OPR speed.
The OPR request flag is turned ON when a
fast -OPR is started (positioning start No.
9002).
The restart command is turned ON after
the machine OPR is stopped using a stop
signal.
The zero point is not passed when the dog
method, count method or scale origin
signal detection method OPR is re-started,
or data set method OPR is executed.
The data is not loaded from the servo
amplifier properly upon the OPR.

Operation status at error occurrence
The READY signal [X0] is not turned ON.
The system does not start positioning.
The communication between servo amplifiers
or later of target axis is not executed.
(The servo amplifier's LED display remains
"Ab".)
The target axis is not connected to the servo
amplifier.
The operation continues.
The machine OPR does not start.
The system stops with the setting
(deceleration stop/sudden stop) of the
detailed parameter 2 Sudden stop selection
(stop group 3).
(Note that the deceleration stop only occurs
during the manual pulse generator operation.)
At start : The system does not
operate.
During operation : The system stops with the
setting (deceleration
stop/sudden stop) of the
detailed parameter 2
Sudden stop selection (stop
group 3).
The fast -OPR does not start.
The restart is not carried out.
The OPR does not complete.
