4-2 Function Mode Reduced Torque Characteristics Multiplied by the time limit characteristics set in b012/b212/b312 for each frequency. (Example) 3G3RX-A2150 (Rated current: 64 A), b012 = 64 (A) , Base frequency = 60 Hz , Output frequency = 20 Hz Torque Trip time (s) x1.0 x0.8 x0.6 Inverter output frequency (Hz) 60 3.0 0 0 5 6 16 20 50 60 0 55.8 (87.2%) 76.8 (120%) 102.4 (160%) Motor current (A) (Ratio to the rated current of the Inverter) 4 Base frequency Constant Torque Characteristics Do not skip this setting when using a constant torque motor.
