7-2-4. Discharge Pipe Control
<Outline>
Detect an input current by the CT during the compressor is running, and set the frequency upper limit from
such input current.

of the lower limit of 4-way valve activating compensation.
When a "stop current" continues for 2.5 seconds after rushing on the stop zone, the compressor operation stops.
If "drooping current" is continues for 1.0 second after rushing on the drooping zone, the frequency will be 2Hz
drooping.
Repeating the above drooping continues until the current rushes on the drooping zone without change.
In the keeping zone, the frequency limit will remain.
In the return and reset zone, the frequency limit will be cancelled,
