201
Start at home
position (OP) fault
When the machine home position
return (OPR) retry invalid is set, the
near-point dog home position return
(OPR) is started with the home
position return (OPR) complete flag
turned ON.
The machine home position return
(OPR) is not started.
203
Dog detection timing
fault
The near-point dog signal is turned
OFF during the deceleration from a
home position return (OPR) speed to
a creep speed by the near-point dog
home position return (OPR).
204
Home position (OP)
detection timing fault
The zero signal is turned OFF during
the deceleration from a home
position return (OPR) speed to a
creep speed by the stopper method
2) - home position return (OPR).
205
Dwell time fault
A dwell time is passed during the
deceleration from a creep speed to a
home position return (OPR) speed
by the stopper method 1) - home
position return (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 home position return
(OPR), a parameter "Setting of
movement amount after near-point
dog ON" is smaller than a distance
necessary for deceleration stop from
a home position return (OPR) speed.
At start: The system will 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 flag
ON
The OPR request flag is turned ON
when a fast - home position return
(OPR) is started (positioning start

Home position return
(OPR) restart zero
point not passed
The zero point is not passed when
the dog or count method home
position return (OPR) is re-started, or
data set method home position
return (OPR) is made.
211
ZCT read error
The data is not loaded from the
servo amplifier properly upon the
home position return (OPR).
212
ABS reference point
