4-button servo controller instructions

[R8R]

On my servo, the instructions show this in the parameter table:

P-06: 1~9, default 6 "Increase time from 0 to 4500 (spm). Time = 900 / value (ms)"

This is a soft-start adjustment. Which is to say it adds time to how it ramps up from 0 to max rpm. 900 divided by the entered value = milliseconds? So setting it to 9 equals 100 ms. Setting it to 1 equals 900 ms (almost one full second till it reaches full rpm)

I can confirm this is correct. When set at "9" and I floor the pedal, it instantly goes full blast. When set to "1" and I floor it, it ramps up to full blast. Takes slightly less than a second.

 

P-08: 0~5, default 0 "Motor braking intensity. Higher the value greater the intensity. Only effect when P-04 is OFF."

I can confirm this is correct. With the positioner turned off, this function clamps down on the machine's rotation when set to "5". I can floor it and it stops immediately when I take my foot off. When set to "0" it drifts ever so slightly to a stop. I can imagine having this would be helpful if a heavy reducer wheel is installed, those things have some momentum.

BTW - P-04 on my motor is the positioner function, which can also be toggled directly by the needle up/down button.

My servo arrived unexpectedly this morning (the tracking still showed it in transit "somewhere"!).  I was concentrating working on a trigger in the shed when he came in, gave me a helluva fright!!

Anyhow, for what it's worth these are the "instructions" that came with mine. Looks like I can reverse the motor just by pushing one button (dumb idea!) and turn a LED on /off. I'll have to see what sort of voltage that connector is putting out. They must use gorillas on their production line judging by how tight the mounting screws were!!

Here is how deluxe confusing mine gets...

Very interesting. There are definite similarities. Although my instructions stop at 22, I think it continues to step past there so I'll have to do a bit of experimenting. P11, speed lock, has me intrigued (?). This seems to add credence to the idea that many of them may use the same circuit board and just disable the features not needed.

Mine doesn't have any markings to indicate brand so it's presumably just a generic unit supplied to various companies, the build quality, while ok, is definitely not up the the standard of my other servos (made by Lishui).

Speed lock disables the plus/minus buttons from directly changing the top speed.

Ahh, that makes sense. One question solved.Thanks mate.

The 16 year old Chinese girls that put it together would get a giggle out of that! Lol

Must be something in the water over there then.....

R8R, even though my instructions don't show them, I can cycle through and see the same settings that yours has. The rear connectors are the same, other than the 2-pin on mine is set for an LED. I've got it working but found that to get the slow speed control I want I have to set the max speed low, about 800. Above that it takes off pretty suddenly and doesn't seem to have the slow ramping that my others have. It's rated at 550w (who knows what it actually is) but appears to have plenty of grunt, doesn't have any trouble stitching through 1/2" of veg with #138/size 140 needle.

Hi, I've been thinking about adding a direct drive Kotor to my singer 491D but I really cannot find a great deal of information on these. My main reasons are better torque and reduced gubbins around the table. Would you be able to offer any advice/feedback on your installation?

Would you recommend the direct drive option over a belted motor or not?

The issue for me is likely that it will be difficult to mount and will requite some fabrication and I've heard they are noisy and have quality control issues.

A direct drive sounds good but a "normal" servo is perfectly adequate for my needs, simple to fit and can be fitted above or below the table. If it needs to be replaced virtually any servo can be slotted in. It also allows a speed reducer to be fitted, which will give slower speed with increased torque, something you can't do with a direct drive. My servos can also be easily swapped amongst my machines, if needed, something I couldn't do with a DD.

A DD certainly looks neat but adapting one to older machines could be a bit of a pain and from my perspective not worth the trouble. It would be an interesting exercise to try setting one up but I'm happy with my setup(s) so I'm not about to try. For a garment machine they may very well be a great solution but I'm not convinced about their suitability for leatherwork.

Just my thoughts on the subject.
