Chapter 11 Port Explanation
11.4.3 Position Interface (PS) Instruction
Position interface (PS) is also in the 7 pins interface like arc import. Input pins are
+24V(OUT), SIGNAL,COM. +24V(OUT) links with the positive pole of location approach
switch, SIGNAL links with the signal of NPN approach switch, COM links with the
negative pole of location approach switch.
Interpret:Approach switch is NPN type with DC24V.
