Cheers , I’ve now added photos in my albums .

This is the manual, all 418 pages. All the answers

What a long winded manual!

I've just closed the PDF and forgot to note the page number but basically you connect Live to R/L1 and Neutral to S/L2

Presumably the terminals on the inverter have labels but they are not readable on the photographs.

The U V W to motor are on the right and the mains input terminals are to the left

The outputs to the motor are generally labelled U, V and W but it doesn't matter which way you connect them to the 3 motor wires to them. And if the motor turns the wrong way, simply swap any 2 of the wires over.

Are there some motors which aren't reversible?

Michael W

Technically yes, but the type of motors relevant to our workshop machines (induction motors) are all reversible.

Some brushed motors are mechanically optimised for running in one direction (e.g. windscreen wiper motors).

Shaded pole motor? Well may be but not easily.

Cheers, I wondered if there were some induction motors that couldn't.

I suppose though that not many machines have shaded pole motors which as you say are not easily reversed, I have only ever changed their direction of rotation by dismantling and turning over the stack of laminations (same idea works on some induction motors where access to the winding/wiring might not be easy).

I've also just got hold of a used Omron v1000 – the manual takes a bit of ploughing through to find the important bits (understatement!).

One thing I have found is that it is not straightforward to change the motor rotation using the keypad while in normal operating mode – you have to go into setup mode and change the relevant parameter. That means that you will definitely want to add some control wiring at some point – there is a diagram on p52 which shows all the control connections. It shows all the possible connections you can make and you won't want or need them all.

Just to complicate matters, it looks like there are two methods of wiring on/off/reverse, called 2 wire and 3 wire respectively. The diagram on p52 shows the two wire method, which requires 2 latching switches wired to S1 to SC and S2 to SC. S1 gives Fwd on and off, S2 gives Rev on and off.

The 3 wire method is shown at the bottom of p43, and requires 2 momentary switches wired to S1 and S2 to give Fwd and Rev, and a latching switch wired to S5. As for the 2 wire method, the remaining terminal on each switch is taken to SC.

All the above is as I understand it – if there is someone more familiar with this model vfd I hope they will correct any mistakes in what I've written.

Strangely I had one driving the mechanical table on my surface grinder. When I reverted to a single motor, and crossed belt to drive the table, I tried everything to reverse it. In the end I binned it and added a proper 3-phase motor. I didn't need to bin the motor that was driving the spindle, it smoked itself.

All I’m bothered about just now is wiring up the vfd to get me up and running ,plain old simple on and off is all I require , can’t see me needing reverse on the Centec2 somehow .

[Steve PaveyParticipant @stevepavey65865]

Ok, just looked at your previous photos, I see from your photos that it's a horizontal machine, I assumed you had a vertical spindle as well.

[sean logieParticipant @seanlogie69385]

I don’t have a vertical head nor am I ever likely to have .

[sean logieParticipant @seanlogie69385]

I've added a couple more photos of how I've wired the feed to the vfd . It powered up but I get a H66 error on the digital readout ,the error code comes up as "Safe Disable inputs ". Think it might be time to call a halt to try and use this 3 phase motor , its kinda taken the fun out of things for me now  . 😔😣

Looking at the instructions on page 245 Hbb seems to suggest that you may need to put a link into the safety interloc terminals as it thinks the circuit is open eg a safety microswitch is activated. I can't see a H66 code listed.

[sean logieParticipant @seanlogie69385]

Hi Jason. the error H66 is on page 180 table 5.5 ..

Are we looking at the same model …..

Sean. Have you got links in place linking HC,H1 and H2 ?

Hi Martin ,no I haven't ,was waiting until the rain stopped to go out to the shed LOL

[Martin CargillParticipant @martincargill50290]

Ok Try the links and see what happens. I'll PM you my mobile number, although I'm going out so I may not be able to answer.

Martin. P.S. I think that some of your problems with the drive come from it being second hand. Whoever has removed it from its previous installation has probably removed all of the wiring, including some that should have been there when the drive came from the manufacturer (like links to HC,H1 and H2)

Edited By Martin Cargill on 13/08/2017 12:45:10

[sean logieParticipant @seanlogie69385]

Right …Am I linking HC,H1 and H2 all together ?

Sean

[JasonBModerator @jasonb]

I'm looking at the pdf that KWIL linked to this also suggests you need to link the same connections wheich would have gone to interlocks if you were using them

If you look at the second column above or in your page 180 you will see the code is Hbb not H66, a six would have the bar along the top on a digital screen

Sorry Jason your right

[JasonBModerator @jasonb]

This is what you want, a couple of short bits of wire stripped at either end.

Thanks Martin really appreciate the help from you .

vfd now up and running
