4.Frequency set range:
Enter the settings interface when short press any button ¡®FREQ+¡¯ or ¡®FREQ-¡¯ in the normal running status to select frequency range.Automatically switch frequency range.
Pay attention to the position where the decimal point moves when the button is pressed.
Display ¡®XXX¡¯.No decimal point,The minimum frequency is 1Hz.The frequency range is 1Hz ~ 999Hz.
Display ¡®X.XX¡¯.The decimal point is the penultimate, The minimum frequency is 0.01KHz.The frequency range is 1.00KHz ~ 9.99KHz.
Display ¡®XX.X¡¯.The decimal point is the third last,The minimum frequency is 0.1KHz.The frequency range is 10.0KHz ~ 99.9KHz.
Display ¡®X.X.X¡¯.The decimal point is fully lit,The minimum frequency is 1KHz.The frequency range is 1KHz ~ 150KHz.
For example:
Display ¡®100¡¯ means PWM output frequency is 100Hz;
Display ¡®1.01¡¯ means PWM output frequency is 1.01KHz;
Display ¡®54.1¡¯ means PWM output frequency is 54.1KHz;
Display ¡®1.2.4¡¯ means PWM output frequency is 124KHz;
5.Duty cycle set range:
Enter the settings interface when short press any button ¡®DUTY+¡¯ or ¡®DUTY-¡¯ in the normal running status to select duty cycle.Automatically switch frequency range.
Duty cycle range is 0.00%-100%.
6.Use steps:
1>.Connect to power supply;
2>.Short or long press button ¡®FREQ+¡¯ or ¡®FREQ-¡¯ to set frequency;
3>.Short or long press button ¡®DUTY+¡¯ or ¡®DUTY-¡¯ to set duty cycle;
4>.Connect to load.
7.UART communication and parameter settings
The system supports UART data upload and parameter setting functions (TTL level);
UART: 9600, 8, 1
1>.Set PWM frequency:
¡®F101¡¯:Set frequency is 101Hz.¡®101¡¯ can by replace by 001~999;
¡®F1.05¡¯:Set frequency is 1.05KHz.¡®1.05¡¯ can by replace by 1.00~9.99;
¡®F10.5¡¯:Set frequency is 10.5KHz.¡®10.5¡¯ can by replace by 10.0~99.9;
¡®F1.0.5¡¯:Set frequency is 105KHz.¡®1.0.5¡¯ can by replace by 1.0.0~1.5.0;
2>.Set PWM duty cycle:
¡®DXXX¡¯:Set duty cycle is XXX. ¡®XXX¡¯ can be 000-100.
E.g:¡®D051¡¯ means PWN duty cycle is be set as 51%.
3>.Read set parameter:
Send ¡®read¡¯ and then get parameter.
4>.Return value:
Return ¡®DOWN¡¯:Set success.
Return ¡®FALL¡¯:Set fail.
8.Application:
1>.Square wave signal generator, generating square wave signal for experimental development;
2>.Used to generate a square wave signal that controls the motor driver;
3>.Generate adjustable pulses for use by the MCU;
4>.Dimmer;
5>.Speed governor;
9.Note:
1>.It`s 1-channel PWM output signals are the same.They can not adjust independently.
