DPTH-100T Inverter communication driver’s read schedule

Read schedule setting parameters are as follows:

1) STATION – Controller address = 0 ~ 255.

2) Read Command – Command = DATA. ( Refer to <Table 1> )

3) Read Start Address – Don't care.

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read Size – Fixed to 1. ( Refer to <Table 1> )
