Control modes
2-1. Frequency is restricted by the compressor electrical current (CT1).
2. Frequency
3-1. Voltage is corrected by bus voltage.

Frequency control such as Hz-down and no more Hz-up will be conducted
according to the compressor electrical current (CT1).
Models
PUHZ-RP1.6, 2, 2.5, 3VHA
PUHZ-RP4~6VHA
Inverter voltage will be corrected by dc bus voltage.
Even though the power supply voltage varies within i10%, the voltage should
be corrected in order to make the output voltage of inverter stable.
Output voltage of inverter is corrected by compressor's electric current (CT1).
