Richard P Posted August 26, 2017 Report Share Posted August 26, 2017 I wrote a stepper motor program coping the Visologic example and cant get any output to work. I wired output 0 and 2 to step and direction on a china TB66000 drive . How do I trouble shoot the voltage output. Is there a working example that will run "as is" on this plc?

MVP 2021 Ausman Posted August 27, 2017 MVP 2021 Report Share Posted August 27, 2017 Hi Richard, first of all ensure that you have the wiring and jumpers correct. I'm assuming that you have used this manual: http://unitronicsplc.com/wp-content/uploads/2015/12/Vxxx_J_TRA22_RA22_INSTAL_GUIDE_12-14.pdf cheers, Aus Quote Link to comment Share on other sites More sharing options...
Richard P Posted August 31, 2017 Author Report Share Posted August 31, 2017 I had the outputs wired pnp. changing to npn solved it. Quote Link to comment Share on other sites More sharing options...
