If this is wrong, the direction of rotation will not be correct later. It's time to solder the precision potentiometer, make sure that the screw matches the print on the PCB. It is best to use a piece of tape to prevent the pin header from falling out when soldering.

When soldering, make sure that you press the screw terminals firmly against the circuit board so that they do not wiggle later. Now you have to connect the screw terminals to each other. After you have soldered the resistors, you can cut the overhanging wire. If you turn the board over to solder the resistors, you should put a piece of cardboard on top to prevent the resistors from falling out. Position the resistors in the right place, you don't have to pay attention to the installation direction.

Bend the legs of the resistors immediately at the body, so they fit well on the board. Do not mix the resistors, otherwise you will have a lot of work. It is better if you cut through the paper so that you separate all resistors, then you can remove the paper without bending the legs crooked. The resistors are usually delivered glued on a paper tape. In the second tutorial we will install this Controller into the control of a China CNC milling machinewith frequency converter and high frequency spindle.
