I purchased a usb RS485 port that looks similar to the one you have. I have the VF-s11 driver successfully loading and exposing its HAL pins. The HAL pins are connected and are switching with my spindle start-stop commands. I have also set the baud rate, parity, number of bits, stop bits, and target where applicable in both the .ini file and on the inverter panel.
And I get nothing. I wonder if i’m not missing something. I do have an actual VF-S9 instead of the VF-s11, but the VF-s11 documentation states that the I/O should mostly match. I suspect that maybe I am using the wrong pair of wires on the RJ45 connector. I couldn’t find any Toshiba documentation on that so I just used what appears to be a standard for RS485 half-duplex on that connector; the blue = A and the blue-white = B. The manual indicates that the inverter is always listening for serial communication, and that sending the inverter enable signal automatically cedes control from the inverter panel to serial. For this reason I assume that I don’t need to enable serial communication on the inverter in order for it to work.

The vfs11 driver runs in user-space so the fact that you can't have realtime control through USB is not such a problem. This means that a cheap USB-RS485 dongle probably is as good a way to do it as any. This is how I connected my VFD. https://forum.linuxcnc.org/forum/18-computer/30675-on-motherboard-modbus-rs485-connection -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
