(3) Selection of A172SENC module and connection with external equipment
(a) Number of A172SENC modules
Determine the number of A172SENC modules according to the number of
control axes which use such external signals as upper and lower stroke limit and
near-zero point dog signals and the number of manual pulse
generators/synchronous encoders used.
You can use up to four modules for the A173UHCPU or only one module for the
A172SHCPUN or A171SHCPUN.
