Chapter 4 - Parameter Description [FU1]

FU1-23 selects the limits for the inverter operating frequency. If FU1-23 is set to ‘Yes’, inverter operates within the upper and lower limit setting. The inverter operates at the upper or the lower limit when the frequency reference is outside the frequency limit range.

☞Note: Frequency limit does not work during acceleration and deceleration.

FU1-26: Manual/Auto Boost Selection

FU1-27: Torque Boost in Forward Direction

FU1-28: Torque Boost in Reverse Direction

This function is used to increase the starting torque at low speed by increasing the output voltage of the inverter. If the boost value is set higher than required, it may cause the motor flux to saturate, causing over-current trip. Increase the boost value when there is excessive distance between inverter and motor.

[Manual Torque Boost]: The forward and reverse torque boost is set separately in FU1-27

and FU1-28.

☞Note: The torque boost value is the percentage of inverter rated voltage.

☞Note: When FU1-29 [Volts/Hz Pattern] is set to ‘User V/F’, this function does not work.

[Auto Torque Boost]: Inverter outputs high starting torque by automatically boosting according to the load.

☞Note: Auto torque boost is only available for the 1st motor. For multiple motors, manual torque boost must be used.

☞Note: The auto torque boost value is added to the manual torque boost value.
