Upper Limit Frequency
Program ⇒ Fundamental ⇒ Frequency Settings
This parameter sets the highest frequency that the ASD will accept as a frequency command or frequency setpoint. The ASD may output frequencies higher than the Upper Limit Frequency (but, lower than the Maximum Frequency) when operating in the PID Control mode, Torque Control mode, or the Vector Control modes (sensorless or feedback).
Note: This setting may not be higher than the Maximum Frequency (F011) setting.

Note: When operating in the Vector Control mode the carrier frequency should be set to 2.2 kHz or above.
The Automatic Torque Boost and the Sensorless Vector Control selections use the motor tuning parameters of the drive to properly configure the ASD for the motor being used. If Load Reactors or Long Lead Filters are used, or if the capacity of the ASD is greater than the motor, manual tuning of the motor parameters may be required for optimum performance.
