Just installing my new VFD have worked through most of the issues but I can’t get the spindle to stop rotating when M5 command is issued. I am using a 0-10v port on the CNC controller box and I can vary the spindle speed using M3 commands but when M5 is issued the spindles slows to 1635 on the VFD display.
Any idea whats happening?
Thanks
I have an idea, check p2.0.13, and try a higher number. Should be .1, math says maybe set it for 1.0 although i haven’t heard of it needing to be that high but 3k rpm is 1.25v and 1500 rpm is 0.625v so yeah, might be about what you need
Its an ignore voltage below this point.
To do it hit mode, then use the up and down arrow and double arrow…
Enter to enter, and then up/down to change, then enter to accept
Thanks, will try and report back.
Something i just realized, you didn’t say the spindle was moving at 1600 rpm.
To change the display hit the double arrow, but it’s just like switching between trip a, trip b and odometer. Youre not changing anything more that what you see.
If the spindle stops turning after hitting m5, leave p2013 alone as there’s no need to adjust it.
Well changing the odometer view made no difference. But changing P2013 to 1 did. As a matter of fact i was able to reduce it to .8 but no lower. Anything lower kept the spindle turning. I will confirm the DC voltage output tomorrow when I get a working multimeter as mine is currently not.
Only thing I am concerned about is that I need to press the run button initially for automatic spinning to occur. Once pressed it seems that you don.'t need to do it again. Is that normal or should the VFD just get the voltage signal and start doing its thing?
Finally, is there any cheat sheet for all of the P settings? Just so I can understand how it is set and what treatment to expect?
Ok. I’m glad I understood the concern. Based on what you said I originally thought that was your complaint, but then reread it and said to myself the concern may just be the readout.
PWM works by the controller sending voltage out, which the vfd interprets as a hertz command, which a hertz then translates to rpm. This is all according to the settings of the vfd.
Like I said that parameter is a "ignore below this level, in your case it might be outputting .74v or something like that which is why you have to have it set for .8
Some controllers require you to hit run, others don’t. There’s nothing we’ve found where you don’t have to hit run, on Controllers you previously did. This is based on power cycle of the controller I believe. (I never did testing, but if you feel so inclined as i dont have a machine that requires it). Hitting stop on the vfd with the vfd in auto mode on one of these controllers is the safest mode of operation when you don’t want it to run unintentionally. I never hit stop when I had one of these controllers, i turned it on, then hit run, then turned it off. But that’s me.
The manual would be your source. Largely speaking there’s no need to change most (99%) parameters.
OK, this will take some getting used to and some broken bits (I hope not). I’m accustomed to hitting run on my control software and not having to worry about the state of my spindle.
Thanks for the info in any case.
