Motor driver board
Each conveyor is powered by a brushless DC motor fitted with gearhead, controlled by a AXHD50K motor
driver. The driver is illustrated below.
There is a motor driver board for each conveyor fitted to the machine. In the main electrical cabinet the
infeed and scale motor drivers are fitted. The outfeed electrical cabinet holds the outfeed motor driver(s).
Note: on - board speed potentiometer – This should not be adjusted, as conveyor speeds are initially
set by an external potentiometer and then controlled from the machines software.
