I could use a bit of basic guidance on which parameters on the VFD I should look at to get the spindle running properly. I'm in a bit over my head with the setup. From reading the VFD manual, it appears that the VFD default settings are for use with a more standard drill press / lathe type motor. I have the wiring down ok ( I think ).

The VFD is a TMX model TD-200 VFD, 115 volt single Ph in and 230 volt 3 Ph out.

The spindle is a fairly generic 1 HP model KL-800A with spec's as follows :

Input Voltage	: 220V Single Phase or 3 Phase
Speed	8000-24000R/min
Power	800W
Frequency	400Hz

I did adjust the VFD's maximum frequency to 400 but that's it. I keep getting an OL2 error message on the VFD ( I suspect that may mean nothing outside of the TMX world.) The manual describes the cause of the OL2 error as : Voltage setting V/F mode is too high resulting in over-excitation of the motor; Motor rated current set incorrectly; Load too heavy.

Any pointers would be greatly appreciated.

Hi,
you severely risk blowing up your VFD.....stop.

Most VFDs come from the factory set up for 50Hz or 60Hz motors. These motors are rated at around 230VAC at 50/60 Hz.

A VFD as you know produces a variable frequency AC voltage. Lets say the VFD is producing a 20Hz voltage. If that were direct connected to a 60Hz
motor the current would be through the roof!!!. For a 20Hz voltage to be applied to a 60Hz motor the voltage must be reduced to 20/60 x 230=80VAC.
If a 30 Hz voltage is applied it must be no greater than 30/60 x 230=115VAC.

This is called the V-to-F curve. Generally as the frequency is low so must the voltage otherwise the current in the motor will be too high and blow up
the VFD and/or motor.

Your spindle is rated at 230AVC at 400Hz. At 100hz the voltage must be reduced to about 100/400 x 230=57.5VAC. If you have not changed the V-F
parameters in the VFD for your spindle the VFD will be applying full 230VAC to your spindle at only 50/60 Hz, and that without protection kicking in will blow
your VFD/motor.

Yes you have a lot of Parameters to set for your spindle I will take a look at the manual I give you what you need to set, Don't keep trying to run it without the Parameters set or you will Damage your spindle or VFD Drive

I received some advice in an email from the VFD supplier. This is their response :

If you have a TD200-1001-1PH, the input voltage to the VFD should be 120VAC single phase.

You may want to factory default the TD200-1001-1PH:

13-08 = 4 (230/460VAC 60Hz) (this is the output voltage)

then set your motor specs your motor specs are set in the Group 2

02-03 = 1800 RPM is factory Default

02-06 = 60Hz is factory default. Set 02-06 to the motor nameplate.


After the motor specs. have been set, set 00-12 for your 400hz max.


That didn't seem to help though.

No that is not correct most VFD Drive sales don't know how to deal with these High speed high frequency spindles

What is your spindle amperage should be a round 5A

Is your spindle air cooled or water cooled

[David Morrow]

It's air cooled.

I'm waiting on the amp rating from the supplier. There was no info sheet with the spindle.

[mactec54]

I have the manual so will work through it 1.5Kw is normally around 5 to 6 amps can't be any more but some of these spindles have a lower rating than what would be normal for 1.5Kw 8000 RPM you could use 133.4Hz for that setting which will be close to 8000RPM you could make it exact if you want to play with the numbers but it not important

[David Morrow]

3.0 Amps

The power rating is 0.800 Kw

[mactec54]

3.0 Amps

The power rating is 0.800 Kw

This is a starting list there will be others to change

TD 200
.8Kw 3A Spindle 24,000 RPM 400Hz

00.8=400

00.11=133.4 ( ?? or 20 )

00.12=400

00.13=133.4

00.14=10 ( Default This Can Be Adjusted Acceleration )

00.15=10 ( Default This Can Be Adjusted Deceleration )

01.01=220

01.02=400

01.03=220

01.08=133.4

02.01=3

02.02=24000

02.04=220

02.05=.8Kw

02.06=400

08.03=110%

11.01=6 ( To 8 )

[David Morrow]

For your setting above 02-02, I don't see that setting in the manual. I assume that you meant 02-03 for Rated Rotation Speed.


I can't thank you enough for all of that work. I would never have figured all of that out. I really don't know what other people do with these things unless they buy their spindles and VFD as a preset matched pair.

I have created a Google Sheet with all of your settings along with the codes and manual descriptions of the settings. Anyone can view; hopefully it will help someone else in the future.
https://docs.google.com/spreadsheets...it?usp=sharing

I will keep an eye out on your post above for edits.

Now to get to work programming this into my VFD.

Yes 02-03= 24,000 I typed the wrong number

Don't be a alarmed if some of these Parameters can not be input, there is another Parameter to change if this happens

Yes there will be more to set with your VFD Drive this is a good starting point, VFD drives are all a little different, no you can not buy a matching VFD to these Spindles they all need programing VFD Drives in general are set up by Default as either a 50Hz or 60Hz to suit a standard AC 3 PH motor I have around 80 different VFD Drive tech information manuals and parameters settings which cover most but there is always a new one that pops up

You can find some that the resellers have tried to setup but fall short of what is needed for high frequency spindles,

Your VFD has 2 modes we will have to see which will work best so there is a lot to do there is also an auto tune feature, but this can only be used once you have the main Parameters set

[David Morrow]

If I'm understanding the manual correctly, on Page 4-32, the default VF settings are for 50Hz or 60Hz. I take that to mean that I will have to create a custom VF due to the spindle's 400Hz frequency. Down on the bottom left, it says to set 01-00 = 7 to create that custom VF. And then on the next page, below the table, it says that all parameters 00-01 to 00-09 must be set to avoid the ERR2 that I've been getting.

Does that sound right ?

[David Morrow]

I tried all of the setting that you suggested but it still didn't work. So, in a bit of desperation, I made the changes to the 01-xx codes as per my last post. It was a bit of a SWAG in selecting the settings. Here's what I did :

01-00 = 7 - for custom parameters
01-01 = 220 - V/F Max Voltage
01-02 = 400 - Maximum frequency
01-03 = 220 - Maximum Frequency Voltage Ratio
01-04 = 260 my guess - Middle output frequency 2
01-05 = 110 my guess - Middle frequency voltage ratio 2
01-06 = 200 my guess - Middle output frequency 1
01-07 = 70 my guess - Middle frequency voltage ratio 1
01-08 = 133 - Minimum output frequency
01-09 = 70 my guess - Minimum Frequency Voltage Ratio

IT WORKS ! But, I suspect that once you look at what I did, you will have some suggestions to make it operate much better.

[David Morrow]

Now that the motor is turning and there are no more VFD error messages, I hope that you will bear with me to tune things up a bit.

The VFD speed Pot moves from the 7:00 o'clock position to the 5:00 o'clock position.

At 7:00 o'clock the LED reads 133.40 Hz
At 12:00 o'clock the LED reads 200.00 Hz
At 5:00 o'clock the LED reads 400.00 Hz

But, at 12:00 o'clock, 200 Hz, the motor is barely turning. It should be running at about 10,000 RPM I suspect.

You are figuring it out very well, as I said in the post yesterday there where other Parameters to change the 01-00=7 was the one to change

You got a little messed up with your Parameters

01-04=Default you should not be using this Parameter this is for the use of a second motor
01-05=Default you should not be using this Parameter, this is for the use of a second motor

01-06=267

01-07=147

01-08=133

01-09=73

Try this and set the 04 and 05 back to the Default

When it is at 133 is the spindle running at around 8,000

[mactec54]

Do you have 00-06=1 set for Pot control

[David Morrow]

I tried inputting your 01-xx settings from above and got all kinds of issues.

01-04, 01-05, 01-07, and 01-09 gave err2 messages when I tried to use your suggested settings. I could not even reset the default values on 01-04 and 01-05. 01-04 automatically inputs =310 and 01-05 automatically inputs 110 when I tried to lock in the changes.

And then things got really weird. When I put my previous settings back in, nothing worked at all.

There appears to be a lot of dependencies within the settings. And, doing them in numerical / manual order creates issues.

I tried to change 01-06 = 1 for keyboard pot control and got an error there too. Go figure.

Yes there can be problems when changing settings as they have to relate to other Parameters that are already set we could change that profile

Don't know what is going on the V/H ratio is .55 so the numbers I gave you should of worked as you had them quite close to what you had any way, I would do a reset and start again, or you may have to clear the fault first

Try setting 01-00=4 and then do a reset

What mode do you have for 00-00=0 or 2

[David Morrow]

I have 00-00 = 0
