3.11 Insufficient Gas Control
Outline If a power consumption is below the specified value in which the frequency is higher than the
specified frequency, it must be regarded as gas insufficient.
With the conventional function, a power consumption is weak comparing with that in the normal
operation when gas is insufficient, and gas insufficiency is detected by checking a power
consumption.
Detail Judgment by Input Current
When an output frequency is exceeds 62 Hz and the input current is less than specified value,
the adjustment is made for insufficient gas.
