Error name
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 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).
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).
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).
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.
The OPR request flag is turned ON
when a fast - home position return
(OPR) is started (positioning start
No. 9002).
The restart command is turned ON
after the machine home position
return (OPR) is stopped using a stop
signal.
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.
The data is not loaded from the
servo amplifier properly upon the
home position return (OPR).
The data is not loaded from the
servo amplifier properly upon the
home position return (OPR).
Communication cannot be carried
out with the servo-amplifier using an
absolute position restoration
instruction.
Error
The machine home position return
(OPR) is not started.
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 will not operate.
During operation:
The fast - home position return (OPR)
is not started.
The restart is not carried out.
The home position return (OPR) is not
completed.
The absolute position restoration is
not carried out.
