When I input 20 mA DC to the terminals 4 and 5, the speed only increases to around 47 Hz.
Pr.905 is set to 50 Hz (100%).
How should I adjust the setting?

Answer

It seems that there is a read error for 20 mA DC inside the inverter.

Setting Pr.905 to 50 Hz while 20 mA DC is actually flowing between the terminals 4 and 5 allows for outputting 50 Hz.
Calibrate Pr.905 again.
