The zero signal is turned OFF during
the deceleration from an OPR speed
to a creep speed by the stopper
method 2)-OPR.
205 Dwell time fault
A dwell time is passed during the
deceleration from a creep speed to
an OPR speed by the stopper
method 1)-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

parameter "Setting of movement
amount after near-point dog ON" is
smaller than a distance necessary
for deceleration stop from an OPR
speed.
