current value that is restored 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.
(2) The dwell time cannot be set.
(3) Even if the speed command is set as probe data by the digital oscilloscope
function, the value on digital oscilloscope does not change with "0".
