Operation outline
If the Pre-excitation/servo ON (LX) signal is turned ON, output shutoff is canceled and the Position
control preparation ready (RDY) signal is turned ON after 0.1 s. When STF (forward stroke end signal)
or STR (reverse stroke end signal) is turned ON, the motor rotates according to the command pulse.
When the forward (reverse) stroke end signal is turned OFF, the motor does not rotate in the corre-
sponding direction.
