when the control circuit power supply of the servo amplifier or the Multiple CPU
system power supply is turned ON again, may be different from the feed current
value before the power supply was turned ON again.
(a) Q173DSCPU/Q172DSCPU
When feed current value update command (M3212+20n) is OFF, the feed
current value is changed to "0".
(b) Q173DCPU(-S1)/Q172DCPU(-S1)
The feed current value is changed to "0" at the start.
(2) The dwell time cannot be set.
