107
READY OFF
ON
during BUSY
The PLC READY signal is turned from OFF
to ON when BUSY signal is turned ON.
The READY signal [X0] is not turned ON.
108 Start not possible
Start is requested when start is not
possible in the axis operation state.
The system does not start positioning.
109
Servo amplifier series
error
The set series of the servo parameter
"
Pr.100
Servo series
" and the series of
connected servo amplifier are mismatch.
The communication between servo amplifiers
or later of target axis is not executed.
(The servo amplifier's LED display remains
"Ab".)
110
Unsupported servo
amplifier connection
A servo amplifier/driver which is not
supported is connected.
The target axis is not connected to the servo
amplifier.
190
Operation cycle time
over error
The calculation process time of the
positioning etc. exceeds the operation
cycle.
The operation continues.
Home
position
return (OPR)
201 Start at OP
• 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 machine OPR does not start.
203
Dog detection timing
fault
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.
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.)
206
Count method
movement amount fault
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.
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).
207 OPR request ON
The OPR request flag is turned ON when a
fast -OPR is started (positioning start No.
9002).
The fast -OPR does not start.
209
OPR restart not
possible
The restart command is turned ON after
the machine OPR is stopped using a stop
signal.
The restart is not carried out.
210
OPR zero point not
passed
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 OPR does not complete.
211 ZCT read error
The data is not loaded from the servo
amplifier properly upon the OPR.
