设定运行 Set operation

最大电流输出设定 Maximum current output setting

  The output setting of the maximum current is to protect the brushless DC motor from damage during overload operation.

The drive over-current alarm and stop the drive operation to achieve this purpose, the set current value should be equal to the rated current of the brushless motor

Match the values without paying attention to the actual power supply voltage setting range: 1.6 ~ 8A.

加/减时间设定 Add / subtract time setting

  The potentiometer can set the acceleration and deceleration time of the brushless motor. The acceleration time is from the stop to the rated speed of the brushless motor.

The required time, the deceleration time is the time from the rated speed to the stop of the brushless motor. Adjustable by rotating left and right

Addition and subtraction time setting range: 0.3 ~ 15S.
