Which servo motor should I buy in Australia?

[dikman]

Brian, I'll put this in here because it relates to the servo I've mentioned.

Mine is a two-button control. The first 5 parameters can be accessed, the rest only change when the needle position synchronizer is fitted and turned on (there are others on the next page but they can't be accessed). The first two are the main ones.N.1 has a range of 10-80 (100-800 spm), N.2 from 1-45 (100-4500 spm). These are the values shown on the display, which are different to those in the book!?!

For the two button operation -

press "-" until N.O displayed

press "+" to select the parameter wanted

press "-" to show the value

press "+" or "-" to change value, wait for the display to return.

Is that what you wanted to know?

Thanks everyone, very helpful info. I'll do some more comparisons. Seems like the brand doesn't really matter too much?

Silverback - can you tell me the specific name of the facebook page? I did some general searches for leather Australia but couldn't find much. 

thanks

Carrie, from what I could find out they're much of a muchness. The housing will change (some are all-in-one, some have separate controls and different control panels) but that's about it. I suppose there may be some quality differences, but how one can tell I don't know. I'm interested in this facebook page too (just out of curiosity).

Thanks dikman, It looks a little easier than what I got. When I bought it The seller could not work out how to change the options on site here. He sent me this attachment  a week or 2 later along with explaining that the machine is presently set at running from 3-15 but will run from 3-55. I rang him and said I'm nor sure what to do and was assured that I am very capable and he knows I can work it out. Well I guess I may be alright with mechanical things but with electrical things I am one big nervous Nelly and to be honest too chicken to try playing with it for fear of ending up with a non working machine altogether. This is why I am now contemplating going to a whole new motor set up that I may understand better or at least someone else I know who may be able to help me with it. Does this look easy to you may I ask?Attachment pdf below,

I see what you mean! Doesn't say much for the seller, imo, makes me think he doesn't understand it either.

Ok, to get into the adjustment setting, press and hold the P key and turn on the power.

It should display SH, which is the first parameter and sets max. speed.(Release the P key when it does).

Press P again, which should let you change the settings. Pressing N will increase the value, S will decrease it. Should go up to 5500 rpm, if the seller is right then it's currently set for 1500 rpm.When you've got the right setting press P again, which exits this parameter. I think this means it will then display SH (which is the current parameter).

Pressing S should change to the next parameter, SL, lower limit of minimum speed. (Pressing S goes forward, N goes back when searching the parameters). If you press P it will enter this parameter and display the current setting. If you don't want to change it press P to exit it.

Once you've changed all that you want to, turn off the power, then turn it back on and you will be back to normal operating with the new settings.

I have no idea what some of those parameters are for, obviously some are for the needle positioning system, but as for the others....

I also found a handbook for this motor (well, the controls are the same at least), don't know if you've got it? Anyhow, look at page 10, those three buttons can be used to change settings without getting into the "technician mode". Top one lets you fiddle with the needle position setting, but if you hold it in for at least 3 seconds it will reverse the motor direction!!! The middle button, Speed Mode switch key, lets you change between two speed modes, low speed and non-low speed (that's what it says). I'm guessing that these setting might be governed by the Kp/Ki parameters, but that's only a guess. It will also let you engage soft start mode.Third one is a Speed Setting key, it looks like you can use it to set the speed between min and max (presumably the settings entered via the "technician mode".

If I had it with me I might be able to figure out some of those parameters - maybe!

Anyhow, hope this helps a bit?

Carrie, apologies for digressing slightly in your thread.

Link to handbook, wouldn't let me download it.

Thank you so much dikman, I feel a lot more confident to have a go at adjusting it now. I will do so this weekend and let you know how it goes. The handbook is the same as the one I have and will retry with those instructions first. I really can't thank you enough for all this and I hope to be able to return the effort in kind sometime.

I do apologise for temporarily hi-jacking your post Carrie.

No worries, Brian, only too happy to help. Don't forget you sent me those thread samples, at no charge, when I was first trying to understand thread sizes, types and what would work in my machines.

NC, a friend bought a 555 and reckons the servo was brilliant, but the machine didn't suit his needs and it was going to be too much trouble to swap the servo over and try and get it working. You've done well, just out of curiosity what was involved in getting it working on the Consew (in case I come across one at a good price )?

It's a bit of a beast of a servo. Pretty heavy. No programming as such. It is set up with several switches and a few trim pots. The main mod I had to do was fit the position/speed sensor to the Consew hand wheel. I couldn't swap the hand wheels over so had to drill and tap the Consew handwheel to mount the sensor bracket. I then drilled and tapped another hole to mount the post that stops the sensor from rotating. I tried running it without the sensor and the motor took off at full speed with no speed adjustment. I then plugged the sensor in but the motor wouldn't run. It needs the feedback from the sensor. I had to modify the belt slot but that was nothing major. The belt was just at a different angle. You then have to set up the sensor for the correct needle position but that is also pretty straight forward. I'l take some photos and post in another thread. Sorry for the hijack Carrie

There is always the Cowboy HVP-70, 750W servo with 50mm pulley for $345.

PM me your postcode for shipping quote.

Thanks Darren, that looks reasonable. For some reason the messaging function is not working for me. Is there another way I can contact you?
