What's best to do with new HY plugin to accommodate these slower cheap RS485 converters, use a timer thread or a editable to user Thread.Sleep. UCCNC is very fast and I still didn't decide or research There really is no difference between these plugin's other than the speed they poll in. HY12 is polling function 01 (Read the data of a function code) this is reading your setting in PD142 (Rated Motor Current) and replying 10. Mach3 plugin communication log is polling function 04 (Read Control Status) for RPM and the reply's are 0. The plugin's communication protocol are all the same as Huanyang VFD has it's own. With the China 400hz spindles this wouldn't make a difference. In HY plugin results are multiplied by 10, multiplying them by 100 will fix this. If your min rpm is set at 100 rpm 16HZ would be lower and possibly why not setting on UCCNC. Mach3 plugin is sending hex A6 = decimal 166 I see from the Mach3 and HY14 communication logs you are trying to set your spindle at 100 rpm on start which would need a 16.6 frequency sent. pro file from start would of helped determine your issues as it seems you may have more than 1. Knowing the spindle you were using and posting your. Thanks for help I hope that the test could help. I don't know the communication protocol of vfd but seems that the polling sequence are different in the three case In the attachment the serial monitor trace in the case: mach3, UCCNC Hy14 UCCNC Hy12 new dongle with driver ch341ser of 2014 year (Get link) -> Hy12 GO, Hy14 NOT go, Mach 3 GO new dongle with driver ch341ser of 2007 year -> Hy12 NOT go, hy14 NOT go, Mach3 GO The problem now it's solved changing the dongle. HY12 is continually polling its status like all Modbus programs, and some of these cheap converter chipsets can't keep up for whatever technical reasons of have no clue of.ĭan Dan911 Posts: 613 Joined: Mon 1:22 am Location: USA If you quickly and repeatedly change rpm speed in Mach3 you will see your RS485 converter will fail there also. Why it seems it's working in Mach3 with HY plugins availible is that there plugin is just sending 1 single line byte array. With HY10 you will get a window reading "VFD not Responding". "01 01 03 8E 00 64 5D 8E" is the byte array HY12 sends to VFD to test communication, if no response plugin won't start. What's only working on good days is your RS485 converter. Porta aperta dal processo "UCCNC.exe" (PID: 4056) Sometimes it go but with fix RPM (don't change with s command) When i open UCNC he talk with VFD that aswer (see below) Spindle talker go well (open port and go with the slider don't go with the Fixed RPM button 6000, 8000, etc)
