POINT
(1) For QD77MS16, M code ON signal, error detection signal, start complete signal and
positioning complete signal are assigned to the bit of "
(2) For QD77MS16, axis stop signal, forward run JOG start signal, reverse run JOG start
signal, execution prohibition flag are assigned to the buffer memory
(3) When using the upper/lower limit signal, stop signal, near-point dog signal of the
external input signal via CPU, use the buffer memory in "
operation device".
