Note: (1) ST500 inverter ST500-132G3/ST500-160F3 to ST500-630G3/ST500-700F3 with "R
suffix" indicates an integrated DC reactor, such as ST500-160G3R.
(2) The correct frequency converter selection method is: inverter rated output current is more
than or equal to the rated current of motor. The difference between the frequency inverter and the
rated power of the motor generally is recommended to be no more than two inverter power steps;
Large frequency inverter with small motor, must accurately input motor parameters, so the inverter’s
protection functions can avoid motor overload and damage.
