Finished Plugins for Download / Re: A new Huanyang VFD plugin
« on: February 03, 2013, 05:55:09 PM »
Thank you for your info.  As you probably and tell I am a newbie to VFD world and also kind of a newbie to Mach 3.  Recently I sent the sellers of the unit I bought ( 3KW motor and VFD) some questions regarding cooling and disconnecting from power when not in use.  On cooling the questions were what the flow rate was needed for the motor and could ethylene glycol be used in the coolant.  The answer i got for the flow rate was "enough to keep the motor from burning up" and on the ethylene glycol was on the first answer no it would melt the plastic in the motor then on the second answer yes you con use ethylene glycol.  On the subject of disconnecting, in their manual the state and I quote "do not use the electromagnetic contactor as the on/off button of power supply for the inverter" and in another place "no fuse  breaker" could be used.  The question I ask them was why a contactor could not be used to remove power from the VFD system WHEN NOT IN USE.  My scheme was to have a 10 amp 3 phase breaker in the panel and a 3 pole relay controlled by a toggle switch for disconnecting the power when not in use.  Could someone enlighten me as to what their thinking is!!!  By the way I am a retired electrician and have an assoc. EE and am lucky enough to have 3 phase power in my wood shop at home.  Not trying to be smart, I just can not see there concern.

Thanks For the answer, sorry I didn't acknowledge you before this but had family crisis that needed to be dealth with.  Also another question or two.  I have a DRO's on the mach3 screen that is labeled AMPS and SPEED what or how do you code that DRO to read AMPS from the VFD, and the Same question for the speed DRO.

I just purchased one of these VFD's and have decided to try to use VFD plugin to control the VFD through Mach 3 on my CNC router setup.  I have a couple of questions regarding wiring connections.  Does the VFD commumicate with Mach 3 via the RS485 connection.  Is the RS485 connection the only one between the mach 3 computer and the VFD.

Thanks so much for the help.  There are some nice guys in the world.  Sincerely, I do appreciate the help.  I am having some fun with this,  it marries two of I passions, computers and woodworking.  I've already tackles some screen mods for Mach3 and they actually work!  Been doing a lot of reading and some trials, not unlike some other programming I have done in the past, as i get a better understanding of mach3 and g-code this will be a lot of fun.  Thanks again to both of you.

That sounds like and excellent idea, the omly problem here is that I am a newby, so help me with a clue with that line of code.

Thanks John that was the problem.   I had looked at the Gen Config file earlier but missed the IJ mode box.  I a greatful to you for the help!

I am new to using mach3 and I have a problem in that I am using one computer (my laptop) to check gcode file and do testing on for scripts and the other to actually run my CNC router. one computer will read a gcode file differently than the other computer. The following code was load to the two computers.  This basically cuts a circle a little over 1 inch and .1 inch deep.  On my laptop this code runs properly but on the CNC router computer it somehow adds the     I-0.552 in line 5 to the diameter of the circle causing the end result to be an elongated x axis on the circle.  By changing line 5 to read G03 X0.552 Y0 I0 J0 F5 the cnc router will cut the circle properly.  Has anyone got a cue to what I am doing to cause this problem?
