☆
In the speed control mode, the maximum output torque of the inverter is restricted by F2-09 or
F2-11. If the torque upper limit is analog, pulse or communication setting, 100% of the setting
corresponds to the value of P2-10 or P2-12, and 100% of P2-10 or P2-12 corresponds to the
inverter rated torque.

P2-13 to P2-16 are vector control current loop parameters. They are obtaind by rotation motor
parameters complete self-learning and generally no need to be changed.
Too large current loop PI gain may lead to oscillation of the entire control loop. Therefore, when
current oscillation or torque fluctuation is large, manually decrease the proportional gain or
integral gain here.

★
It means that the inverter's maximum output voltage can be increased. Increasing P2-20 can
increase the maximum load capacity in the field weakening area of the motor, but it will increase
the motor current ripple and increase the motor heat. Normally no need to be adjusted.
