Mechanical installation Chart 1: Mechanical Dimensions6. Power supplyNormal operating voltage is from 20V to 36V. The driver can be supplied by unregulated DC power. Step-down transformer + bridge rectifier + capacitor filter also. Capacitance can greater than 2200μF. But care should be taken that the rectified voltage ripple peak value is no more than 20V.If you use regulated switching power , note that the output current range of switching power need to be larger than 10A.Please note: 1.Best to use non-regulated power 2.When using non-regulated power , the output capacity of power current should be higher than 60% current of controller. When using power, the output capacity should be higher than current of controller. 3. In order to reduce the cost, 2 or 3 controllercan share the power. But should improvethe rated power &rated output current of power and pay attention to the heat.7.Driver WiringA complete brushless DC motor control system should contain a brushless DC motor, brushless DC motor controller, DC power and control signals. The following is a typical system diagramChart 2 Drive wiring diagram8.Fault Phenomenon and Ruled OutWhen the power is on, the emitting tube is with 1-second light and 1-second dark. CW terminal or CCW terminal is with low level. The emitting tube light for long time when the driver operates.Defaultphase: emitting tube flare for 2 times and dark for long time-- Check the Hall signalRestricted rotation or over current: emitting tube flare for 3 times and dark for long time-- Check the Hall signal & Check whether the dead load & Check whether motor with short circuit
