(c) System MCU can detect the status of the power module DSP chip via ID1_OK (28), ID2_OK (29), ID3_OK (30), ID4_OK (31), ID5_OK
(40) and ID6_OK (41). "Logic Low" means that the power module DSP chip is functioning properly. (ID5_OK and ID6_OK are not used for
reserve.)
(d) ON is connected to the relay driver of the auxiliary power supply inside the power module. If POWER_ON (42) is "Logic H," then the auxiliary
power supply inside the power module is on.
