I found a manual here: https://inverterdrive.com/file/Toshiba-VFS15-User-Manual I usually first check the overview graphic which seems to be on page B-4. I see the F terminal which could just be shorted to common to activate it. The speed potentiometer is shown too. PWM could simulate that. I also see theRS485 connector. I did a search in the document for "485" and found page C-4, which shows some control options; terminal (relay), keypad, RS485 (Modbus?), CAN (cool), communication(what the heck?). Just below are some speed setting options. This should be a nice VFD. A little farther down from B-4 are the I/O circuit options. Looking at the F entry, it basically says shorting the F terminal to CC will start forward rotation. You can use a parallel port pin to control a small solid state relay or opto-isolator. It just needs to tolerate 24 Volts on the output. It looks like the VIA (voltage, input, analog?) is a speed input. The same parallel port pin to solid state relay or opto-isolator as F above may be used, except it only needs 10 Volt tolerence. Terminal PP is the 10 Volt source (CC common isn't needed, most likely). The signal from the parallel port pin should use PWM or PDM. If you have a BOB (Break Out Board), post a make/model and/or picture or other information. It may be useful for the above connections. It looks like page D-3 is a good place to start VFD programing. The above may be wrong or missing some information, so study the manual and decide for yourself what to do. I would get a mains input noise filter right of the bat, so you don't have to chase down weird issues while trying to learn how to use your VFD. Hmm... It looks like your VFD already has a built-in noise filter. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
