Input Current Control
Outline
The microcomputer calculates the input current while the compressor is running, and sets the
frequency upper limit from such input current.
In case of heat pump model, this control is the upper limit control function of the frequency which
takes priority of the lower limit of four-way valve activating compensation.
Detail
Frequency control in each zone
Dropping zone
The maximum limit of the compressor frequency in this control is defined as operation
frequency – 2Hz.
After this, the output frequency is pulled down by 2Hz every second until it reaches the steady
zone.
Keep zone
The present maximum frequency goes on.
Reset zone
Limit of the frequency is cancelled.
Stop zone
After 2.5 seconds in this zone, the compressor is stopped.
Limitation of current dropping and stop value according to the outdoor air temperature
1. In case the operation mode is cooling
The current drops when outdoor air temperature becomes higher than a certain level (model by
model).
2. In case the operation mode is heating
The current drops when outdoor air temperature becomes higher than a certain level (model by
model).
