VFD HY only rotates at 12000rpm

[SaporeCNC]

Hi, thanks for your attention
I told you that I measured the tension and the ip-m csmio does not exceed 5v

I made some changes to the parameters of the VDF and it gave me some results

first change pd070 is (speed control input) set to 1 is 0-5v and in 2 I get no response, the axis does not turn

the jumper is in the VI position

and also change the following and I got this result

pd011 configured 100.00 axis rotates at 6000 rpm 1.5v
pd011 configured 200.00 axis rotates at 12000 rpm 2.3v
pd011 configured 300.00 axis rotates at 18000 rpm 3.5v
pd011 configured 400.00 axis rotates at 24000 rpm 4.8v

all these speed changes I get it by changing the parameters
in the VFD no matter what I entered in the mach tab in MDI

regards

have you tried the jumper in the other position (vr)

Hi, thanks for your attention

I'm sorry, this might be a language thing. Where/when did you tell us this? Or is this you now reporting the results of the S24000/S12000/S6000?

Okay, so if the CSMIO output voltage varies (wrt the Sxxxxx MDI input) 0-5V, then a value of 1 for pd070 would be correct...

pd011 configured 100.00 axis rotates at 6000 rpm 1.5v
pd011 configured 200.00 axis rotates at 12000 rpm 2.3v
pd011 configured 300.00 axis rotates at 18000 rpm 3.5v
pd011 configured 400.00 axis rotates at 24000 rpm 4.8v

I'm unsure what you're talking about here. You're changing the minimum frequency (a function of RPM) from 100 - 400 (6000rpm - 24000rpm), which suggests to me that the VFD is reading a minimum demanded spindle speed, and it's driving at the values in the pd011 as a consequence. You should reset pd011 to 0 (or your required minimum) and not try to use this as a method of speed control.

BUT, what is the reference to voltage (1.5v, 2.3v, 3.5v and 4.8v)? - are these the outputs from the CMSIO analogue channel 0 with the different S6000, S12000, S18000, S24000 MDi commands?

I understand you're saying that there is no response to entering speed commands in the MDI. But are those analogue voltages (tension?) the result from the speed command at the CSMIO output / VFD VI-ACM input?

If that interpretation is correct, then there's at least some suggestion that the Mach/CSMIO is correctly configured (although the register 64 in the settings looks at odds with the CSMIO/IP-M instructions here.... https://en.cs-lab.eu/wp-content/uplo...-m-artykul.pdf which seems to indicate a register value of 80... which also suggests that the CSMIO IP-M output is expected to be between 0-10V. But I'm not familiar with the CSMIO and wouldn't comment further on this.


I would reset PD011 to 0 and PD070 to 1. Then I'd get a 1.5V cell (AA battery), disconnect the RFD VI input from the CSMIO and connect the cell with + to the VI input, and the - to the ACM input. Using a M3 command from mach3 should then give you 24000/5*1.5 = 7200 rpm (or there abouts). This would confirm the analogue input into the VFD is working as expected. Or not.

I use a CSMIO/IP-M, and it takes a little bit of work to get it set up for analogue speed output. I would like to see a measurement of the CSMIO output voltage at the terminals just to check that it is actually configured correctly. The CSMIO plugin for Mach3 has some settings that are not obvious (although if you work through the manual very carefully they are documented) and you have to get this right. You should see 0-10V coming out of the CSMIO when it is configured correctly. Quick check with a voltmeter will confirm whether the CSMIO has been set up correctly.

Hello everyone
thanks to the help they gave me and was able to configure and apparently it works well,
when entering a G code, the VFD and the axis respond to the required speed,
in the week I will make some cuts and see how everything behaves ...

the changes you make to make it work were the following

pd011 configured at 150.00 is the minimum recommended in air-cooled axles and goes to 6000 rpm
pd070 set to 0 and thus works from 0-10v

thanks again for your time !!!!
