Elimination of Heat
Drive’s reliable working temperature(heat sink) should be <70 (158
℉
), and motor working temperature(surface) should be
<80
℃
(176
℉
);
It is recommended to use automatic idle-current mode, namely current automatically reduce to 60% 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.
3. Connectors and Pin Assignment
The EM stepper drives have two connectors, connector for control signals connections and connector for power and motor connections.
Most EM drives adopt screw terminals for signal and power connections as follows. The following figure is connectors and pin
assignment of EM806. The other EM drives have similar interface. Please refer to drive’s datasheet for the detail.
