Mitsubishi Electric 800 Series Instruction Manual page 567

(N) Operation via communication and its settings
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 Pr.902 and Pr.904 settings from the inverter of station No. 0.

a ENQ 00 FF 0 01 7D
b ENQ 00 EC 0 01 79
c ENQ 00 5E 0 0A
d ENQ 00 60 0 F6
To read/write Pr.902 or Pr.904 after inverter reset or parameter clear, execute from (a) again.
