Porter Current Limit Adjustment

It is possible to adjust the Porter current limit setting by fitting either a fixed resistor or a potentiometer across the pads circled in red below

Porter current limit

A resistance of 100k gives a motor current limit of around 60A for the Porter 5 and around 120A for the Porter 10, but be aware that component tolerances can have a significant impact in this area, if you need an accurate current limit you should measure it and adjust the resistance value accordingly.

If using a potentiometer keep the leads as short as possible to prevent noise pick up.
