I have used the VFD (Micromaster 420 2.2kw) and new 2.2kw Chinese spindle. The VFD was configured as:
Р0003=1
Р0004=0
Р0010=1
Р0100=0
Р0304=220V
Р0305=8A
Р0307=2,2kw
Р0310=400Hz
Р0311=24000
Р0700=1
Р1000=1
Р1080=50Hz
Р1082=400Hz
Р1120=10s
Р1121=10s
Р3900=3
After pressing the start button, I saw an error A0501. I tried to turn the spindle again and it worked. But the error appeared again the next time it was turned on.
Do I need to change the VFD settings so that the error does not appear again?
Thanks!

I only see ( 1 ) important Parameter in your list that may be the problem, P1080 depending if you have a water cooled or air cooled spindle, this Parameter should be 100 for water cooled and 200 for air cooled

The fault is over temperature

Another Parameter to look at is P0640 change to 100%

P1080 ?? ( Air Cooled / Water Cooled )

P0314= 1 ( number of Poles 1 pair )

P0640= 100%

P1135 ??? ( Ramp Down Time may need to increase from Default of 5s )

[Andrey67]

I tried P1080=100 (water cooled) and had the same error.
There is another similar VFD with the same settings. With the second VFD, I had another error F0001. And this error is not permanent either.
I returned the spindle to the first MM420 but the three wires to the spindle were connected differently.
Now the Micromaster works without errors. But it's fast, I'm afraid to see white smoke from the spindle.

P0314= 1 ( number of Poles 1 pair )

How can I see these parameters? P0003=2 or 3???

What do you mean the three wires were connected differently?

[mactec54]

What do you mean the three wires were connected differently?

The U V W connections can be wired different, to the spindle Motor, Most of the Manufactures recommend that U =Pin 1 V=Pin 2 and W=Pin 3, on some spindles this makes no difference which pin is connected, but other will fault or run poorly if not wire connections are not to the Spindle manufacture's spec's

P1080 has to be set to 100, this is the minimum speed your spindle can run, running below this minimum speed will damage your spindle

Most likely you only need P0003=1 this will do all the basic Parameter setting, it is only for a different level of access, to change different Parameters, you should not need any higher than 2

If you can't set the Parameters I suggested then you may need to go to level 3

So do you your spindle wired U=Pin 1 V=Pin 2 and W= Pin 3

Thanks.... I can understand if there are four pins and you use the wrong ones ....but with three there should only be a change of motor running direction...

[ericks]

Quick google search....seems they come with four pin plugs. Looking at the amount of failures that guys get on these motors i suggest they "ring" out the wiring/windings before they connect them up

Yes you would think so, but not all these spindles work how one would normally expect a 3Ph motor to work, I have never bothered to find out the reason, all I know is that some of these Spindles fault or run poorly if not wired as the post above, the 4th pin if they have it is Ground

[Andrey67]

So do you your spindle wired U=Pin 1 V=Pin 2 and W= Pin 3

U=Pin 2 V=Pin 3 W=Pin 1 GND= Pin 4

[mactec54]

U=Pin 2 V=Pin 3 W=Pin 1 GND= Pin 4

If all is working as it should, then no problem with what connections you have used

[Andrey67]

I did so U=Pin 1 V=Pin 2 and W= Pin 3 it works too.
Should I use P0314=1 P0640=100% P1135 still?

How can I stop the servo on my CNC if the error is again? Should I break the control power (VDC)?
How?

Yes those Parameters should be set, not sure I under stand what you mean , Control Power, or Main Power , if this is your Mains Power Supply to the VFD then No if the spindle is still running, only if the Spindle is stopped

[Andrey67]

My English is bad, maybe you did not understand me .
I have a homemade CNC machine.
While the machine was on, the spindle stopped working and the VFD published the error again. If the axises keep moving, the end mill will get broken. What signal from VFD can to stop the servo?

How are you starting the VFD, from the control Panel, Start / Stop or by relay from Breakout Board to turn the VFD on

[Andrey67]

Now I'm using the BOP.
My CNC is in the process of building only.
I want:
---if the VFD has an error - the servo stop
---if any servo has an error - the other servo stop also

Ok you can use the Mach3 Charge Pump circuit this circuit can be used in the VFD by more than one way, you can use the Relays that are in the VFD so when the circuit is broken ( Fault ) it will STOP Mach3 to ( RESET Mode )

What parameters and pins of the VFD should I use for this?

You could try either of these 2, not sure which one would work best, the Parameters are in the snip

Digital Input 1

Or Digital Input 3

Thank you!
