Minor error [303], [304]
When the speed change is executed after
positioning automatic decerelation start or during
decerelation by the JOG start command signal
(M3202+20n, M3203+20n) OFF, since the
speed change request is ignored, a minor error
[303], [304] will not occur.
When the speed change is executed after

Processing with power supply OFF
of servo amplifier
Servo OFF is executed for all servo amplifier
connected behind servo amplifier with which the
control power supply was turned OFF.
Servo OFF is executed for only servo amplifier
with which the control power supply was turned
OFF.
Back-up battery for internal memory
Internal rechargeable battery
(Set the external battery (Q6BAT) if continuous
power off time is longer for 1 month or more.)
(Note-3)
Internal rechargeable battery
(Set the external battery (A6BAT/MR-BAT) if
continuous power off time is longer for 1 month or
more.)
(Note-4)
(Note-1) : Use the Dividing unit (Q173DV) or dividing cable (Q173J2B CBL M/Q173HB CBL M).
(Note-2) : When selecting the each servo amplifier general input, the speed/position switching control cannot be executed. And, the external
stop input cannot be used.
(Note-3) : When adding the external battery (Q6BAT), use the Q170HBATC.
(Note-4) : When adding the external battery (A6BAT/MR-BAT), use the Q173DV (Q173HCPU use) or Q170BAT (Q172HCPU use).
