To use the limit switch function, set two DI terminals of the servo drive respectively with function 14 (Fu-
nIN.14:P-OT, positivelimit switch)and function15(FunIN.15: N-OT,negativelimit switch)to receivethe
limit switch input level signals, and set the terminal logics. The servo drive determines whether to enable or
disable the limit switch function based on the DI terminal level.
