Question：
Why does the motor governor need to set the frequency?
The frequency of the motor governor is too low, the power supply ripple is large, the vibration of the motor is large, the frequency is too high, the switching loss is large, and the electromagnetic noise is relatively obvious. If the frequency selection is not suitable, the effective power output of the motor will be greatly reduced. The default frequency of this product is 20KHz, which can meet the requirements of most motors.
Why does the motor governor use a digital encoder knob instead of a normal potentiometer?
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.
Features:
Working voltage: DC9V~60V, input anti-reverse connection protection
Rated current: 12A maximum current 20A
Maximum power: 500W
Working frequency: 1KHz~99KHz adjustable, 1KHz step, default frequency of 20KHz, accuracy of about 1%
Duty cycle: 0-100%, 1% step
Product size: 79mm*43mm*26mm
Install hole size：76.5mm*39.3mm
Product weight: 43g（Naked heavy）65.5g(With the packing)
Packaging: carton packaging
All parameters can be set to power down storage.
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 limit, duty cycle upper limit and working frequency.
ON-OFF is to set the module to be normally open or closed by default. Rotate the encoder to switch to the default on-off state.The display form of duty cycle lower limit is "L" + two digits, the display form of duty cycle upper limit is "H" + two digits or "100", and the display form of working frequency is "F" + two digits.
Long press 2s -- exit the setting interface
Counterclockwise rotation - the corresponding Settings are reduced
Clockwise rotation - the setting parameters increase accordingly
The stop button interface on the back：
External switch keys or 3.3v level.Do not use in complex electromagnetic environments because there is no protection inside the circuit.(note that the external switch should use the self-reset button or key, press to open and then press to close;It cannot realize the function of output on when the switch is always closed and output off when the switch is not closed.
