Full-range Automatic Torque Boost (when V/f Mode is
Selected: n002=0)
The motor torque requirement changes according to load conditions.
The full-range automatic torque boost adjusts the voltage of the V/f pat-
tern according to requirements. The V7 IP65 automatically adjusts the
voltage during constant-speed operation, as well as during acceleration.
The required torque is calculated by the Inverter.
This ensures tripless operation and energy-saving effects.
Normally, no adjustment is necessary for the Torque Compensation
Gain (n103, factory setting: 1.0). When the wiring distance between the
Inverter and the motor is long, or when the motor generates vibration,
change the automatic torque boost gain. In these cases, set the V/f pat-
tern (n011 to n017).
Adjustment of the Torque Compensation Time Constant (n104) and the
Torque Compensation Iron Loss (n105) are normally not required.
Adjust the torque compensation time constant under the following con-
ditions:
• Increase the setting if the motor generates vibration.
• Reduce the setting if response is slow.
