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.
