User Manual of A90 Series Inverter increased. For the speed sensorless vector control, this parameter can be used to adjust the speed accuracy of the motor. Increase this parameter if the motor speed is low under load, and vice versa. Vector control is used to set the operating conditions of the torque limit. If the output torque of the inverter is greater than the set upper limit, the torque limit function will be enabled, thus controlling the output torque not to exceed the upper limit of speed control torque. F06.09=0: depending on F06.10 and F06.11 The upper limit of electric torque is F06.10, and that of braking torque is F06.11.
F06.09=1:AI1 F06.09=2:AI2 The upper torque limit is dependent on AI (percentage) * F06.10/F06.11. For the details of AI1 and AI2, refer to the F00.04 description. They have the same meaning. 100.00% is the percentage to the set value of F06.10/F06.11. F06.09=5: communication setting The upper torque limit depends on the communication. If the master-slave communication (F10.05=1) is enabled and the inverter works as the slave (F10.06=0), the upper torque limit is “700FH (master-slave communication setting) * 250.0% * F10.08 (slave receiving proportional coefficient)”, and the 700FH data range is 0.00% to 100.00%.
