I'll have to pass on that one, I like the look of the quill feed being separate from the top of it but that's well out of my budget.

another Herbert this is mine

 

[atconut]

mine has a threaded collar just above the chuck. if you put a ring spanner between the collar and the chuck and screw the collar down it will pop the chuck off the tapered spindle. mine only has a no 1 Jacobs taper on the spindle so the biggest chuck I can fit is a 3/8

All wired in, I turned it on and...


It didn't move. It made a high pitched noise, then the inverter stopped and the display now shows "E.LF". I'm trying to find the fault codes but if anyone knows what I've done wrong, please help.

Well a bit of a pic wiring insight would help and the model of inverter?

Just found it, it means "output phase loss"

Name --- Output phase loss

Description --- This function stops the inverter output if one of the three phases (U, V, W) on the inverter's output side (load side) is lost. Whether the protective function is used or not is set with Pr. 251 Output phase loss protection selection.

Check point --- Check the wiring. (Check that the motor is normal.)
--- Check that the capacity of the motor used is not smaller than that of the inverter.

Corrective action --- Wire the cables properly. y Check the Pr. 251 Output phase loss protection selection setting

The second check point must be the problem, it's a 2HP inverter but only a 0.33HP motor, though I thought this was fine, provided the inverter is bigger than the motor?
@brewdexta, you led be to believe this was the case?

 

[Maker]

How can I check the motor?

I was hoping it wouldn't need any settings changed to change motors, that way I can swap between lathe and drill with a simple changeover switch. I'll try to understand the instructions. They're here if anyone's interested

 

[julianthegypsy]

You might have a loose connection on one of the phases. It's happened to me a couple of times on normal three phase electrics. Switch the drill on and it just hums, but spin the chuck and off it goes...in either direction too as far as I recall!

 

[normspanners]

Dont foreget you are supposed to set the motor rating into the vfr !! so that it knows what to expect you might be able to test by starting the other kit running with no load and piggy backing the drill into it, to at least test.

 

[brewdexta]

I must admit I was under the impression that the size of the motor doesn't make much difference, a 2hp motor will be drawing a fraction of that 2HP with no load. I guess there could be some optimisation if max load is known but I wouldn't have thought it would stop it altogether.

You can check the motor with a meter, make sure you can see continuity between A and B, B and C and C and A. You should take the metal straps out that converts it from start to delta otherwise you will also see B to A via C when measuring A to B. Also the resistant of each winding should be similar and if you have the straps out there should be no continuity between windings. Also check they don't go to earth i.e. the casing etc.

There will be a spark along soon with better advice.

 

[Wendelspanswick]

You definetly need to put the motor load into the VFD.
On mine programs 141-144 deal with motor size:
141 = voltage
142 = current
143 = poles
144 = rpm
If they don't match the motor rating plate the VFD refuses to run and gives an error code.

 

[brewdexta]

I'm still not convinced that all this would stop it, some may, I would check the windings first.

Obviously if the input voltage was wrong that would be an issue. Possibly output voltage however it is already driving a delta wound motor on his Chippie from 240 single phase mains to a 240v delta wound motor so as long as the new motor is strapped to be delta wound and the plate on it, although not that clear looks to be dual voltage and it its got the straps for delta/start then the settings should be good.

I have a whole workshop digital inverter from Direct Drives, I have yet to get power it up () but you don't have to change any values if your using different motor loads, windings or speeds.

The settings on the Mitsubishi are different to Wendels

A bit more detail on page 100 which talks about auto tuning. It would be interesting to see what settings you have Adam.

There was continuity between A1 & A2, B1 & C2 and C1 & B2. I think the connections for C1 and B1 are crossed over. I think swapping them back will sort it. There was no continuity between any other ones, none to the case and all the pairs are the same resistance.

 

[Maker]

This is without the connection block in place:

The two wires in the lower left are crossed over which wouldn't have been a problem star wired as I bought it but will not work for delta.
Swapped back and now everything has continuity where it should.

How do I go about programming the inverter then? Or will it work as it is now?

 

[daleyd]

The power rating won't (shouldn't!!) stop it working but it will provide protection for the motor. It prevents the drive from overloading the motor in the event of a stall or fault.

To program the inverter you either use the front keypad or you can also get software and a programming cable for some models to use via laptop. Some models will have a quick start guide to put in main parameters.

Main settings are power (can be set as current or sometimes kW) , max frequency, min frequency, accel and decel times voltage etc.

 

[Maker]

It works. I haven't touched the settings in the inverter, just sorted out the motor and it came straight on. I'm reading the instructions to see if it can hold settings for more than one motor as it will also be used to power my lathe and hopefully another drill.

If I had a three phase mains supply, would it have this protection?
