Questions and Answers:

 

1. Q: How high is the PWM frequency supported by the module?

A: In the 25 °C environment, it is recommended that the PWM frequency be no higher than 150KHz to control the switching loss of the MOS transistor. The output waveform and rising edge, falling edge, and input/output delay test waveforms of the driver module at different PWM frequencies are provided below for reference.

2. Q: Will changing the working mode change when the DIP switch is changed during work?

A: No, the working mode is the new setting mode after power-on.

3. Q: What model is the MOS tube?

Answer: The MOS tube is NCE6075K. Each bridge arm of the H bridge uses two MOSs in parallel.

4. Q: Is the circuit schematic and layout available?

A: The schematic and layout of the circuit are not provided by the ZR5002 module.

5. Q: How much power can I drive?

A: According to the safe work area icon, the maximum current when the power supply voltage is 23V is 20A, because

This maximum output power is 460W.

6. Q: In PWM mode, when the input signal is 100% duty cycle, is the output duty cycle also 100%?

A: No. In PWM mode, the maximum output duty cycle is 99.7% when the input signal duty cycle is 100%. When the input duty cycle is small and 99.7%, the output duty cycle is the same as the input duty cycle.

7. Q: When using the analog control method, how many potentiometers should I use when connecting the potentiometer?

A: Potentiometers between 4.7K and 220K can be used.
