Tor
que Boost
• In the 3G3MX2-V1 Series Inverter, the default data for A041/A241 were changed to Automatic torque
boost (A041/A241 = 01).
With this setting, the inverter increases the output voltage automatically depending on the load condi-
tion. In other words, the output voltage generated when the automatic torque boost is enabled is the
sum of manual torque boost voltage and the automatic torque boost voltage.
• To use the automatic torque boost function effectively, set the 1st/2nd Motor Capacity (H003/H203)
and the 1st/2nd Motor Pole Number (H004/H204) correctly according to your motor.
• To avoid possible overcurrent tripping during deceleration, set the AVR Selection (A081) to 00
(Always ON).
• To enable the slip compensation function in addition to the voltage compensation provided by the
automatic torque boost function, first set the 1st/2nd Automatic Torque Boost Slip Compensation
Gain (A047/A247) to 100%.
• If the automatic torque boost does not provide the intended performance characteristics, adjust it for
each adjustment item shown in the following table.
