Elimination of Heat
Driver’s reliable working temperature should be <70
℃
(158
℉
), and motor working
temperature should be <80
℃
(176
℉
);
It is recommended to use automatic idle-current mode, namely current automatically reduce
to 50% when motor stops, so as to reduce driver heating and motor heating;
It is recommended to mount the driver vertically to maximize heat sink area. Use forced
cooling method to cool the system if necessary.
