Inverter Remote Stop button.

Roger, all you need to do is to put another "push to break" switch in series with the stop switch that is already there. Pressing either button will break the circuit and the inverter will be commanded to stop.

Roger, Jo is right. The circuit I sent you is an exact copy of the one supplied by Transwave in their pendants. As Jo says, all you need to do is put another normally on push button in the +24v line from the inverter in series with the existing Off button.

Hi Roger

On the IMO Jaguar VXR units if you want to have external controls / switches you need to change function F01 to 1 by default it is set at 0.

This now activates the external inputs, if you do not want a full pendant function just a stop button.

then it is wired between terminals PLC (which is +24 volt) and terminal FWD (forward)

IN Addition if you do not need the speed control then a wire link (insulated) is needed between terminal 12 and terminal 13. (this will set the inverter to max speed as set by the programing).

When the stop button is pressed the inverter will stop the motor quickly as reactive braking is applied, but NOT so quick as to spin the chuck or what ever off the nose.

If you use a contactor to remove the power input to the inverter, Firstly the machine will take a lot longer to stop ( not good if you are tangled up in it !) and second you stand a good chance of damaging the inverter.

Just a further point the time taken to get to speed and to slow to a stop is fully controllable in the software setup.

Hope this helps

Traction man, now why cant they put the type of information you have just described, in the manual !. Youve made my day. Thank you.

Thanks again to all on this excellent forum.

...but are the Jaguar Cub and VXR the same in all these aspects? I'm interested as I'm currently considering getting a Cub or a VXR.

Hi Martin

I have three Jaguar Cub inverters and the "Quick reference guide" that was included with them is for the VXR I have checked and I can find no difference between the full manual information and the Quick guide.

That is not to say there is no difference internaly in the inverters, there are differences in the software as it would appear that the VXR has a different power curve to the CUB. Hence the price difference between the CUB family and the VXR. But the way the external connections are used looks to be the same between both families.

I have found a phone call to Transwave to be very helpfull. I have to say that I am just a very satisfied customer and have no connection with the firm.

Like Roger when I fitted a CUB inverter to my tool and cutter grinder I did not want a full pendant and the inverter was installed inside the cast stand so it was not accessable for just stop start functions.

Cheers

Hi Roger

I have been re checking the CUB programing manual and the previous information I gave is not the full story

You do need to set F01 to 1 this sets the frequency input (terminal 12) to be active so that when it is linked to terminal 13 (which is +10 volts) the inverter will ramp up to full speed as programed.

In addition you need to change the setting of F02 to 1 this sets the source of run command to external input, so that the external FWD and REV terminals are active.

Cheers

Hi Traction man.
From your comments in your last post will not leaving F01 set to 0 and just setting F02 to 1 not achieve what Roger requires ?  (Use internal speed pot but have external emergency stop.) This is assuming the stop button he plans to use is a mechanically latching one rather than the normal push to break type.

There's plenty of advice for Roger within this post but I for one am still unclear as to what Roger wants his 'big red button' to do does he (a) want it to function as a Emergency Stop or (b) does he want it to stop his lathe along with the normal stop/start ?

Hi Les

You could be right, the instructions are an extract from the pendant programing instructions. I programed my unit as I have said, but looking at the main manual it is not clear if there is a dependancy between F01 and F02, it would need a call to Transwave to clarify.

Harry I looked at Rogers origonal posting and my understanding is that he does not have a pendant and he only want's to fit a latching stop button. The problem is that if you program for external inputs then the buttons on the inverter itself do not function as stop / start.

At least that is my current understanding with the units I have.

Hi Roger,
Reading back through the posts again it seems that all the control that you want is a start button, a stop button and and extra stop button. (ie you do not want any speed control, reverse or jog function) Is this correct ?
If so why not just just build a box with just a start button, a stop button and a relay and locate it next to the inverter. Even if you bought all the bits from Maplin it would probably cost less than £10.00 You could then connect the stop button that you want to use in series with stop button in the box. This sounds like a problem that could be solved more easily if someone could come and help you. Have a look to see if any of us replying to your post live near enough to help you. If I do I would be prepared to help and I suspect the others would also.

Les.

Hello, I just need a Stop button on the headstock, thats mimics the one on the inverter itself. If I needed to switch the motor off a bit quick, I would have a game reaching it in time, because of the distance involved. I think I will buy a pendant and put a decent Stop button on it after all, and stop ( sorry!), causing all this trouble! Thanks anyway.

Hi Roger

Its not a problem (as far as I am conserned) the thing is these inverters are very versatile as they are used in hundreds of different applications, not just on ME machines. Its a matter of sorting out the functions you need.

I do agree that the manual is hard going to find just the bit one needs, hence my comment about a call to Transwave, as they are using them every day they will know all the options that work.

Cheers

Hi Roger if your going to spend your £70 might want to check this out and go the whole hog , have to ask why don't you resite the inverter ?

Hope you get it sorted soon

Hello Harry, due to very limited space, I cant resite the inverter, but even doing that, to hit that tiny red button on the keypad, in a panic move at that, would be hard to do.In the manual,( online version), they advise against mounting on the machine itself, because of heat and vibration, so the nearest place fot it would still be about 3 - 4 feet away !.

From all the info on this site, and from the crappy manual, I think its either a pendant for control, or keypad, nothing in between. Im trying a stop / start set up today and see what happens, or failing that, as someone has mentioned, Maplins for a complete DIY pendant job ! . Knowing bugger all about inverters, I thought it would be a simple job to just put a big red button, right there ............... Regards, Roger.

Hi Roger understand what your saying about space so if you are going for a pendant you will find some cheaper alternatives on the link below, secondly as said previously I'm sure if you make your location known someone would come and give you a hand !

Hello all, a result at bleeding last. Right, Factory settings for Jaguar Cub 2.2kw, FO1 - 4, FO2 - 2.

To fit E stop, change only FO2 to 0, wire external switch to PLC and FWD, Bingo !. The controls on the keypad still work as normal . More by luck than judgement I think, but got there in the end. Hope this helps others with the same inverter. Only downside, release the stop, and motor starts up again, but no matter.

Again, thanks to all for your patience. Regards, Roger.

roger,

Welll done, just a shame about the release and start, lets hope you dont forget.

Martin P

Hi Roger,
Is there a start button in the box that contains the stop button ? If there is then the addition of a 24 volt relay would make it so this button had to be pressed to restart the lathe. It would also have to be pressed when you first powered the lathe up. Maplin sell a relay that would do the job for £1.99 If you were really tight on space in the box I think I could modify the circuit to use a small SCR such as an 2N5060 plus a couple of resistors.

Les.

Hello Martin and Les, unfortunately, I couldnt cram anything else in the box, but I could always change it at a later date as another project . Im not too worried at the minute, because the old gal has a clutch as well.

Regards, Roger.
