NOTES Refer to page 6-450 for data formats A, A', B, B', C und D.
Set 65520 (HFFF0) as a parameter value "8888" and 65535 (HFFFF) as "9999".
For the instruction codes HFF, HEC and HF3, their values are held once written but cleared
to zero when an inverter reset or all clear is performed.
Example When reading the C3 (Pr. 902) and C6 (Pr. 904) settings from the inverter of station No. 0.
Tab. 6-140: Example for data transmission
To read/write C3 (Pr. 902) and C6 (Pr. 904) after inverter reset or parameter clear, execute from
