4.6.2 Simple position feed function by contact input (Pr. 419, Pr. 464 to Pr. 494)
REMARKS
⋅ For the servo ON signal (LX), set "23" in Pr. 178 to Pr. 189 (input terminal function selection) to assign the function.
⋅ For the in-position signal (Y36), set "36" in Pr. 190 to Pr. 196 (output terminal function selection) to assign the function.
CAUTION
Changing the terminal function using any of Pr. 178 to Pr. 189, 190 to Pr. 196 may affect the other functions. Set parameters after
confirming the function of each terminal.
♦Parameters referred to♦
Pr. 178 to Pr. 189 (input terminal function selection) Refer to page 231
