Hi

After several days with reading and testing I realize I need help with the parameter settings for the VDF. I have a Sunfar E550 VDF and a water cooled 60.000 rpm, 1000Hz, 1,2KW China spindle. I do use the Csmio IP-S to control my cnc and the spindle. The software I use is Mach3 .

I did first run the spindle with the original settings in a few sec, I did stop before any error/warning, I understand now this could destroy the spindle. I do not know if the spindle is ok or not.

After playing around with all the F,s for a while I was able to run the spindle in a few sec on low rpm before the error Fu.03 jump in. Under my testing I did also get error Fu.01.

Are there any "forgotten" and/or wrong parameter settings?

My settings look like this:
F0.00 - 1 & 3 ( 1 when I use Mach3, 3 when using the pot.meter on the VDF )
F0.04 - 1000Hz
F0.05 - 10 sec
F0.06 - 10 sec
F0.12 - 1000Hz
F0.13 - 220V
F1.04 - 1000Hz
F1.06 - 0V
F1.07 - 10V
F1.18 - 1000Hz

I hope some can help me with the VDF settings. I am so close to end a 2 years work on a homemade cnc machine.

Update for what I have been trying.

The Error Code I get is Fu.01

(From the manual)
Fault Description:
Over current occurs in inverter acceleration running process.

Possible Reasons:
1. The acceleration time is too short.
2. Start the rotating motor directly.
3. The torque boost is preset as too large.
4. The network voltage is too low.

Solutions:
1. Extend acceleration time.
2. Restart the motor after stop
3. Reduce voltage of torque boost.
4. Check the network duce power.

The parameters I have been playing with is:
F0.03 (Lower limiting frequency)
F0.05 (Acceleration time)
F0.08 (Carrier frequency)
F0.11 (Torque boost)

I have been trying 100+ possibilities with the above parameters with no luck.
Before I started this time I did set the F0.00 to 3 (potentiometer on the VDF) and turn it to max output (60.000 rpm).

The settings I have been using is:
F0.03 (0 - 500 Hz)
F0.05 (100 - 400 sec)
F0.08 (6 - 10Hz)
F0.11 (0,1 - 6)

Even when I set the F0.011 Torque boost to 0,1 & the F0.05 Acceleration time to 400 sec. The VDF give me still the Fu.01 error.
But I can not set the F0.11 torque boost lower than 0,1.
The spindle start spinning but the VDF cut when the display show from 9A - 13A.

Question in my search for the solution:

My spindle is 1.2Kw.
Is that around 5.5A?

When the VDF show the output in A.
Should the max output shown in the display be 5.5A (the rate for the spindle)?

What parameter do I use to set the max Ampere for the spindle?

Is there other parameter that can squeeze the Ampere down?

What is a "normal" acceleration time?

I hope some can give me a hand to fix this "strange" behaviour of the VDF & spindle.

I've been following this thread and was wondering if you found a solution. I'm having similar issues with mine and could use some help.

It would be best to do a Factory Reset, as you have been setting parameters that don't need to be set, at the start

You can not use a Max Frequency lower than what the motor is rated at, in your case 1000Hz

Your minimum Frequency can only be as low as what the manufacture will allow, most likely no lower than 600Hz

To do a Reset set Parameter F3.10 to 3

Some for you to try

F0.01= 1000Hz

F0.03= 600Hz ( if this is your minimum speed )

F0.04= 1000 Hz ( Max speed )

F0.05= 20 or more ( Acceleration ) ( Start at a big number & then change it to a shorter time once you get it going )

F0.06= 20 or more (Deceleration ) ( Start at a big number & then change it to a shorter time once you get it going )

F0.07= 1 ( Try this this will give it a more gentle start up & Stop )

F0.12= 1000 Hz

F0.13= 220v ( Or what your max voltage is )

F1.04=1000 Hz ( Maximum Frequency )

F1.03=600 Hz ( Minimum Frequency ) ( Or what ever your Minimum Frequency is for your spindle )

F2.19=1 ( Number of Poles )

Thanks for your answer, mactec54.

I did try your advice, sadly I still get error.

I did measure all the pin (1,2 & 3) again with another multimeter, this is the result:
2 & 3 = 0,7 ohm
2 & 1 = 2,4 ohm
1 & 3 = 3,7 ohm

Should not the ohm be more or less equal, between the pin but how do I know if the spindle is broken?

Check you motor wires like this

1-2 this is U-V

1-3 this is U-W

2-3 this is V-W

Also check each Pin/wire to Ground

Checking your Pins/wires is the same as what you have already done, so your spindle does not look good if they are the correct numbers
Have your spindle motor checked to be sure, at a motor repair shop

Yes they should be within 2%

Using incorrect settings in the VFD can damage these spindles in the first try

Do you have the same 60,000 RPM Spindle

[tonebag]

mactec,
my spindle is HSD 18,000 RPM 6hp 300 HZ
I tried the above settings and was unsuccessful. my errors had to do with either inverter overload or motor overload.
I still had my old VFD, a Sunfar C300A so I powered it up and went through each setting manually, wrote them down and then applied those to the E550. my issues were with the frequency - I was using 1000 when it should have been 300 HZ max! everything works fine now.

I can post my settings if someone thinks it will be helpful.

Your spindle is completely different to the one w.worker is using

You can not use the same settings as w.worker has to use for his spindle, his spindle is a 1000Hz yours is 300Hz , that is why you have to set your VFD to suit each spindle motor spec, there are many that are different, but all use the same Parameter list, but you have to use the right motor spec numbers

You were lucky you never smoked your motor with using 1000Hz, with your max of 300Hz your minimum setting for your air cooled spindle would be around 200Hz
