2. Frequency
2-1. Frequency is restricted by the compressor electrical current (CT1).
Frequency control such as Hz-down and no more Hz-up will be conducted
according to the compressor electrical current (CT1).
4. Power supply to
locked compressor
4-1. Compressor energizing method
• Compressor ON/OFF pattern when power is supplied;
• Compressor ON/OFF pattern when power is cut off;
5. 52C
ON/OFF method
52C will turn ON/OFF in the following conditions.
• 52C turns ON when power is supplied, and remains ON regardless of the
compressor’s ON/OFF.
• 52C turns OFF when power is cut off.
W Hz-down amount:
-5Hz per minute
“08” will be displayed
on the LED1 of “A-

while power is
supplied to the
compressor.

3. Voltage correction
3-1. Voltage is corrected by bus voltage.
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.
3-2.
Voltage correction by compressor’s electric current (CT1). (PUHZ-RP4 to 6V only)
Output voltage of inverter is corrected by compressor’s electric current (CT1).
W2. Actual values of V/F will be almost the same as the V/F line on the graphic
chart because the inverter control is based on voltage and frequency.
However, they may not exactly match the V/F line on the graphic chart
because voltage correction control makes an effect on the performance.
