Note 1) Applicable motor is reference motor. When select motors, take notice so that rated current of motor
does not exceed over the inverter’s rated current.
Note 2) Output voltage decreases when power supply voltage is decreased.
Note 3) Control torque at capacitor feeding back is an average deceleration torque at the time of shortest
deceleration in motor unit (when stopped from 50Hz), not a continuous regenerated torque. Average
deceleration torque changes depending on motor loss. When operated exceeding over 50Hz, this
value is decreased.
