First, the computer spring machine is different in two cases:
1, the driver parameter problem
The accuracy of the motor is adjusted by the hand-held device, wherein the parameters Kp.Kff.Kvp and Tvi in MODE0 are respectively reduced, but this operation will reduce the mechanical working accuracy. So when we adjust, just adjust the value to moderate, do not blindly pursue the mute effect and affect the accuracy.
2, mechanical precision problems
Carefully distinguish between gear noise or a sharp sound from the rear of the motor when the motor is running. Check the machine for loose parts. Check the gears for clearance. In general adjustment, just loosen the motor fixing screw and tighten the motor.
