Remark:
(1) PI500 frequency inverter PI500 132G3 to PI500 400G3, with “R”means built-in DC
reactor, for example PI500 160G3R, PI500 160G4R .
(2) The correct option of frequency inverter is : Rated output current of frequency inverter
≧
rated current of motor, and the capacity of overload should be considered;
The power difference between rated power of frequency inverter and motor should be less
than two class;
While big frequency inverter loading smaller motor, the correct motor parameters should be
input in case the motor be damaged by overload.
