LS PCU Inverter communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – 0 ~ 31 station address.
2) Read command – command = FAULT, VOLT, INVERT, UTIL, POWER, TEMP, INFO. ( refer to <Table 1> )
3) Read start address – read start address.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – fixed to 1.
