• Full-range automatic torque boost
Motor torque requirement changes according to load conditions. Full-
range autoniatic torque boost adjusts voltage of V/f pattern according to
the requirement. The VS mini 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 automatic torque boost gain (n38
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 pattern (n24to n30).
