Operation
Turning on the servo on signal (LX) cancels the output shutoff and the operation ready signal
(RDY) turns on after 0.1s. Turning on the STF (forward stroke end signal) or STR (forward
stroke end signal) runs the motor according to the commanded pulse. When the forward
(reverse) stroke end signal turns off, the motor does not run in that direction.
