*Recommend use side mounting for better heat dissipation
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
