Error name
The near-point dog signal is turned
OFF during the deceleration from an
OPR speed to a creep speed by the
near-point dog machine OPR.
The zero signal is turned OFF during
the deceleration from an OPR speed
to a creep speed by the stopper
method 2)-OPR.
A dwell time is passed during the
deceleration from a creep speed to a
OPR speed by the stopper method
1)-OPR.
In the count method 1 and 2
machine OPR, a parameter "Setting
of 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.
Communication cannot be carried
out with the servo-amplifier using an
absolute position restoration
instruction.
At the time of JOG starting, the JOG
speed comes out of a specified
range.
The inching movement amount
exceeds the JOG speed limit.
The condition data No. is outside the
setting range when a block using the
condition data is started by a special
starting (conditional start, wait start,
simultaneous start, FOR (condition)).

Condition data No.
Error
Operation status at error occurrence
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.)
The machine OPR is not started.
The fast OPR is not started.
The restart is not carried out.
The absolute position restoration is
not carried out.
The JOG operation is not carried out
when the JOG speed is outside the
setting range at the time of JOG start.
The inching operation is not carried
out when the inching movement
amount exceeds a JOG speed limit at
the time of inching start.
The operation is terminated.
