*Recommend use side mounting for better heat dissipation
Elimination of Heat
Driver’s reliable working temperature should be <70°C (158
℉
), and motor working temperature should be
<80°C(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.
