Unknown Chinese servo motor controller manual needed

[Einherj]

I am looking for the manual for this Chinese servo motor controller.
I want to install a syncronizer, but the parameters on the controller do not match the ones on the manuals I have found online.
I couldn't find any model number on the controller to do a proper search either.

Here's what I found about the parameters by testing:

You enter the parameters menu by pressing the P and + buttons at the same time.
You browse the parameters list by + and - buttons.
You enter into a specific parameter by pressing the P button.
You increase or decrease the parameter with + and - buttons.
You exit the menu with the S button.

P-02: range = 0 - 1, Reverses the motor direction
P-03: range = 06 - 18, increments by 1, current setting 12
P-04: range = 200 - 800, increments by 50, current setting 200
P-05: range = 0500 - 4000, increments by 50, current setting 2000
P-06: range = 000 - 999, increments by 1, current setting 000
P-07: range = 0800 - 2000, increments by 100, current setting 1100
P-08: range = 0 - 1, current setting 0
P-09: range = 0 - 1, current setting 0
P-10: range = 0 - 1, current setting 0, if set to 1 it seems to be some auto sew setting where the machine runs for about 6 seconds, then pauses for a while and repeats.
P-11: range = 0000 - 9999?, increments by 1, current setting 0000, I only tested that it goes over 1000, but since it increments by 1 it would have taken forever to go to 9999
P-12: range = 001 - 120, increments by 1, current setting 005
P-15: range = 0 - 1, current setting 0
P-16: range = 0200 - 4500, increments by 100, current setting 1000


Let me know if you need more info or photos. Thank you.

You did your homework, showing us what the ranges and defaults are for each parameter. At a quick glance that menu looks like the "Stitchman"

I recall seeing that P-10 type setting somewhere.  I think it was some kind of break in or run in thing. Seems like it would run intermittently like that until you shut it off. I think ...

Yes in another manual I've seen it explicitly called "Break-in".

I've updated the doc to say "Break-in"

Thank you very much for this. It helped a lot.
Seems like my controller has the same parameters.

I found out, though, that P-15 on my controller actually is correctly defined: 1 = needle detection, 0 = no needle detection.

Then I ran into an issue with the synchronizer I bought from eBay:
The wiring is different from my controller. The synchro red LED was very dim and on at all times no matter the synchro position. I measured the voltage from the controller pins, and it seems the pins layout is rotated 180 degrees on my controlled compared to the synchro.

Looking at the back of the controller, the measured socket pinout is:
Top left = 5v
Top right = signal 1
Bottom left = ground
Bottom right = signal 2

The synchro plug pinout is:
Top left = signal 2 (white wire)
Top right = ground (black wire)
Bottom left = signal 1 (yellow wire)
Bottom right = 5v (red wire)

I rewired the synchro to match the controller, and now the red LED on the synchro is bright at a certain point on the rotation, which I guess is the intended result.
I had no idea which way the signal wires were supposed to be, but I tried both ways, and the other way the red LED on the synchro never came on.

Now, I have another problem:
When I press the pedal, the machine runs maybe a half a rotation and then the controller gives an error: Er01
After letting go of the pedal, sometimes it still tries to get to the needle up position, and sometimes it just stops.

Any idea what Er01 might be?

I've updated my original post on the stitchman motor to include error codes from the manual I was given.

The synchronizer that came with the stitchman controller has only three wires. Here is a photo of the plug

Thank you very much. Gotta go and troubleshoot some more.

I have a speed reducer between the motor and the machine, so it might be that the motor spins a full rotation and doesn't find the needle position since the machine (where the synchro is) hasn't done a full rotation yet.

[Einherj]

I tested the synchro on my other machine that has the same controller, but no speed reducer, and it worked fine.

I've seen other controllers with some type of "belt scale" setting, where you can compensate for the difference in motor pulley size and machine pulley size.

I found the manual. Turns out, my controller model name is M-6SD2. There are other controllers listed in the same manual.
I was going through my document drawers and it was there, under the pile.
I scanned the English translated pages for future reference.

I can't edit my first post, but I will attach the scanned files here.
