Is not red SGDV-1R9D01A on SGDV-1R9D01A a 2K ohm resistance: SGDV-1R6A01B<br \/> using the pulse plus direction position control mode of <br type \/> position control set several models we tested: SGMJV-02ADE6E<br \/> servo motor drive

Hello, I use S7-1200 to control Yaskawa servo motor reversing, rotation to the instruction is always in one direction, is this what reason? How to adjust? See if the mode of your pulse output is the same as the interface circuit required by the drive input, it should be PLUS+PLUS-DIR+DIR-, the collector open output pulse
