PARAMETERS
NOTE
• 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.
• When a 32-bit parameter setting or monitored value is read and the read value exceeds HFFFF, the reply data will be HFFFF.
Example) When reading the C3 (Pr.902) and C6 (Pr.904) settings from the inverter of station No. 0.
To read/write C3 (Pr.902) or C6 (Pr.904) after inverter reset or parameter clear, execute from (a) again.
