Re: [Emc-users] Modbus VFD Adapter
I don't like USB much for using with LinuxCNC. The VFD/Modbus components work well enough or can be modified easily enough to get what I need. Plus I don't know Ladder. I have a few VFD's that I run three twisted pair to for FWD, REV, and speed PWM. With a micro controller I could get that plus monitor frequency, load, and other things with two pair. well thats interesting! the avr will connect to LCNC through serial port? i like to hear what is the usb disadvantage in this particular application. where i* can find some info about modifying those components (* without much programming skills) theres a link here: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?VFD_Modbus but reading somewhere that it is outdated (kirk wrote thats, sure you meet he:) ), im stalled in CL and mb2hal. regards rick 2013/10/3 Gregg Eshelman g_ala...@yahoo.com: On 10/3/2013 10:41 AM, David Armstrong wrote: On 03/10/13 17:29, Kirk Wallace wrote: I'm thinking about completing some work I did with AVRs and Modbus by making an adapter that has a Modbus port for a PC connection, with digital and analog IO for VFD control.

Re: [Emc-users] Modbus VFD Adapter
It's like you say ... VFDs are so cheap these days.. I consider the GS1 and GS2 series from Automation Direct to be throwaways if they fault out. And they seem to be quite durable on top of that... If you had a bunch of machines that already had VFDs in place and you didn't want to change them out, a board might make sense. Otherwise, I'd simply swap the drives out.

Re: [Emc-users] Modbus VFD Adapter
Hi Kirk, im interested in modbus control, in the past week i was working on controlling some delta vfd and servo drives (only non-rt processes like on/off, rpm set, reverse, warnings, alarm clear, status), do it with an usb/rs485 adapter from ebay (very cheap), and using mb2hal for interfacing with LCNC (have problems with the vdf as it is the cheap of the line and dont accept modbus fnct16 only fnct6). Some examples with mb2hal control an arduino mega, as a modbus I/O control. Im interested, what is your intention with the AVRs adaptor? about the lcnc side of things It could be done with classicladder but editor window has to be open for modbus to work. regards Rick 2013/10/3 Kirk Wallace kwall...@wallacecompany.com: I'm thinking about completing some work I did with AVRs and Modbus by making an adapter that has a Modbus port for a PC connection, with digital and analog IO for VFD control.

Re: [Emc-users] Modbus VFD Adapter
Chris Morly made a change about a year ago so the window could be closed while Classic Ladder was still running. He added a Hal bit to allow that. I'm not sure where it was pushed to, but it was really nice. :-) Dave On 10/3/2013 12:50 PM, Ricardo Moscoloni wrote: about the lcnc side of things It could be done with classicladder but editor window has to be open for modbus to work. -- October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
