2.10.8 Overcurrent Protection Circuit Operation Test
Wire the units as in the figure below, enter all settings (PWM output settings), then
confirm that the criteria are met.
The wiring diagram shows an example of wiring CH5. Actual measurment should be
performed on all channels.
Use an external power supply of 5 V or 12 V, and load resistance of 5 Ω.
Caution
For this test, set an output of 100.000% on each channel under test, and 0.000%
for all other channels. With other tests, the fuses in the internal circuitry can blow
if multiple channels are turned ON at the same time.
