Remark

1 ) In case of VEXTA RK series, TIMMING output turns on when a motor rotates at every 7.2 degree.

For exact ‘return to origin’, we suggest you to configure ‘AND’ operation using TIMMING output and DOG sensor. It may be different to each system features to return to origin by the DOG sensor without TIMMING output signal (The rated input for the origin of K120S is DC 24V.)

2)Using DC 24V, wire a proper resistor to driver in series.

3)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)

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