Hey y'all

I got a preinstalled Juki DU-1181N a while ago with a KRAFT-FX800W Servo motor. Currently have been using it casually with the RPM etc, but I also noticed there's a needle positioner on the motor. Are there any general manuals for servo motors as I can't find anything on this motor documentation wise. When incorrectly pressing some stuff, I occasionally see numbers such as C1, C3 on the screen and I have no idea what they mean. If you know anything about this motor and what button combinations I can use and what the values mean, please reply!

A - Hold to active the needle positioner (?)
B - Change sewing direction
C - Decrement RPM
D - Increment RPM

Not a whole lot to be messing with on these servo's. While I am not familiar with the brand, it is much like any other brushless servo. The speed up and down is all you really need. You'll not need to change the direction of rotation. Needle positioning will require a 3rd component not pictured. It hangs on the hand wheel keeping track of the machine's drive shaft position. Needle position button will allow you to go between needle up, needle down or turned off completely. Your C1, C3 etc. are internal parameters that would require the servo's specific manual to decipher. I've never found a need to mess with anything besides the speed and needle positioner
