Help Require About Mitsubishi Inverter FR-D740-5.5K

Hi;

We have Mitisubishi inverters FR-D740-5.5K at our machines. Normally these inverters display Ampere following and out put frequency but i want to check the total out put power to motor. I have tried to change the display mode by changing the Pr52 and set it at 14 (display output power) but after that drive displays power with points say 0.6....0.67 etc. If I assume that this is the percentage of total output power but inverters are quote with apparent output power not the real power. This made me confuse. So please help me how to check the real output power.
