List 5: Test PWM Output
1
Measurement Setup
- Connect multimeter red probe to GPIO.4 (green terminal)
- Connect multimeter black probe to GND
- (Alternative: Use oscilloscope for measurement)
2
PWM Mode Activation
- Enter command:
M6 T1 - Switch to PWM mode
3
PWM Output Testing
- Enter command:
M3 S5000- Output should change from 0V to 2.5V - Enter command:
M3 S10000- Output should change from 0V to 5V - Enter command:
M5- Output should return to 0V
4
Mosfet ON/OFF Test (Optional)
- Connect red probe to MOSFET Vmot-main (orange terminal)
- Connect black probe to IO.4-MOS-GND (orange terminal)
- Enter command:
M3 S10000- Output:Vmot-main - Enter command:
M5- Output: 0V - used to drive inductive loads such as solenoid valves
Expected Results
- M3 S5000: Output changes from 0V to 2.5V
- M3 S10000: Output changes from 0V to 5V
- M5: Output returns to 0V
- Mosfet output Vmot-main or turn off
