Description:
1. Equipped with start-stop button, and can be external switch control, to meet various customer control requirements
(note: the external switch should use the self-reset button or key, press to open and then press to close;It can't realize the function of opening output when it is closed all the time, and closing output when it is not closed.)
2. Motor soft start function. When starting the motor, the current increases slowly and there is no shock current, which can effectively protect the motor and prolong its service life
3. Duty cycle, duty cycle upper and lower limits and working frequency can be set to facilitate customers to operate and use their motors according to their working characteristics.
4. Digital encoder knob adjusts motor speed, which is more accurate and consistent than ordinary potentiometer.
5. With standard 5135 instrument shell, convenient for customer installation.

Operation of digital encoder knob:
In the default interface :(the duty cycle is displayed by default)
Short press -- switch motor start and stop
Long press 10s -- to enter the setting interface
Counterclockwise rotation -- the duty ratio decreases
Clockwise rotation -- increased duty cycle

Under the setting screen:
Short press -- select setting parameters and switch between ON-OFF,duty cycle lower li
