1-2. 1.2 V/F pattern
W
1. Actual performance does not exactly match the V/F line on both graphic charts due to
the air-conditioning load because the inverter control is based on vector.
W
2. 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.
