16.4.1 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 K3P-07CS, 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.
