Operation status at error occurrence
When the PLC READY signal [Y0] is turned
from OFF to ON : The READY signal [X0] is
not turned ON.
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).
(Note that the deceleration
stop only occurs during the
manual pulse generator
operation.)
The READY signal [X0] is not turned ON.
The communication between servo amplifiers
of target axis is not executed.
(The servo amplifier's LED display remains
"Ab".)
