ZK-MG DC5-30V/9-60V 5A/12A PWM DC Motor Governor Motor Driver Adjustable Speed Encoder Digital Display Duty Cycle Maximum Frequency 15A 20A

Why does the motor governor need to set the frequency?

Motor governor frequency is too low, power ripple, motor vibration;The frequency is too high, the switch loss is large, the electromagnetic noise is obvious.If the frequency is not chosen properly, the effective power output of the motor will be greatly reduced.The factory default frequency of this product is 20KHz, which can meet most of the motor requirements.Consult motor manufacturer for specific frequency selection.

Why does a motor governor use a digital encoder knob instead of a normal potentiometer?

1. Product highlights:

1.1 equipped with start-stop button, and can be external switch control, to meet various customer control requirements
1.2 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
1.3 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.
1.3 digital encoder knob adjusts motor speed, which is more accurate and consistent than ordinary potentiometer.
1.4 with standard 5135 instrument shell, convenient for customer installation.

3. Operation instructions:

3.1 wiring instructions

3.2 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 -- 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 duty cycle lower limit, duty cycle upper limit and working frequency.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 -- exit the setting interface
Counterclockwise rotation - the corresponding Settings are reduced
Clockwise rotation - the setting parameters increase accordingly

3.3 back STOP port
Switch key or 3.3v level can be externally connected. Switch the start/stop state of the motor when the key is closed or 3.3v level is lowered.
