Arrangement of control circuit terminal block
■ Wiring example of control circuit terminal
 "Thermistor input [PTC]" can only be assigned to input terminal [5]. Select on "Input terminal 5
function selection [C005]". For thermistor input, the common is [L] terminal regardless of the
sink/source logic.
 "Pulse input B [PLB]" can only be assigned to input terminal [7]. Select on "Input terminal 7
function selection [C007]".
 Input terminal [8] has a fixed function as the "Pulse input A [PLA]" input terminal. Function
cannot be changed.
 Output terminal [11] switches to the "STO state monitor output [EDM]" by turning on the switch
on the board.
