5) Wiring instructions
A high speed pulse input is sensitive to the external noise and should be handled with special care. When wiring the built-in
high speed counter of GM7U, take the following precautions against wiring noise.
(1) Be sure to use shielded twisted pair cables. Also provide Class 3 grounding.
(2) Do not run a twisted pair cable in parallel with power cables or other I/O lines which may generate noise.
(3) Before applying a power source for pulse generator, be sure to use a noise-protected power supply.
(4) For 1-phase input, connect the count input signal only to the phase A input; for 2-phase input, connect to phases A and B.
