Full-range automatic torque boost (when V/f mode is selected. n002=0)
Motor torque requirement changes according to load conditions. Full range
automatic torque boost adjusts voltage of V/f pattern according to the requirement.
The VS-606V7 automatically adjusts the voltage during parameter-speed operation
as well as during acceleration.
The required torque is calculated by the inverter.
This ensures tripless operation and energy-saving effects.
• Operation
Normally, no adjustment is necessary for torque compensation gain (n103 factory
setting: 1.0). An excessively high setting of torque compensation gain will result in
motor over excitation, and possible inverter faults. If adjustments are necessary, adjust
n103 in increments/decrements of 0.1 for optimization. When wiring distance between
the inverter and the motor are long it may be necessary to increase the setting of n103.
When motor generates vibration, decrease the setting of n103.
Adjustment of torque compensation time parameter (n104) and torque iron loss
compensation parameter (n105) are normally not required.
Adjust torque compensation parameter under the following conditions:
• Increase setting when the motor generates vibration.
• Reduce setting when motor response is low.
