2.10.3 ID Check
This test confirms whether the module is correctly identified when module information is
obtained from the MX100, MW100, or equivalent.
(If the OFF/ON cycle is not performed on the MX100, MW100, or equivalent, the ID
information is not updated. )
2.10.4 Peak Value Test
Wire the units as in the figure below, enter all settings (PWM output settings), then
confirm that the criteria are met.
Use an external power supply of 5 V, and load resistance of 5 Ω.
The wiring diagram in the figure below is an example of measurement on CH5. Actual
measurment should be performed on all channels.
