14.4 External signal selection function
The "external signal selection function" is used to select the external input signal of
QD77MS, external input signal of servo amplifier (PIN No. CN3-2, CN3-12, CN3-19) or
external input signal via CPU (buffer memory of QD77MS) when using the upper/lower
limit signal and near-point dog signal.
When the external input signal via CPU (the buffer memory of QD77MS) is used, the
external input signal status of QD77MS can be operated by connecting the limit switch
to input module and by operating the buffer memory of sequence program. When the
external input signal via CPU (the buffer memory of QD77MS) is used, operation is
affected by the PLC scan time.
The details shown below explain about the "External signal selection function".
