Remark

1)The rated input for the origin of K120S is DC 24V.

2)Input points for origin, approximate origin point, and upper/lower limit signal are fixed but, if they’re not used you able to use them general input point. You can use emergency stop with the command(POSCTR)

3)Positioning phase of K120S is as follow: Set the input mode of a step mode driver to 1 phase input mode is determined by rotating direction input.
