I bought ks100 servo drivers from AliExpress. The datashets are in Chinese and very soft in information. Does anyone know how can I enable the servos? I will run them in 5V mode step dir way in a 7i96s mesa board.
You could try running the manuals through Google translate?
KS100 turns up many different products, most of which are not servo drives. However searching the web for the manual is probably something you already tried?
I found the step per revolution parameter.
However I cannot found how can I manage to make the motor faster. I am using a 1:9 gearbox, I put de step per revolution higher and lower and calculated the stepper scale, but the speed will always be the same, because the stepper scale do that.
