When operating with frequency larger than 60Hz/50Hz, change only max.
output frequency (n09).
• Full-range automatic torque boost
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 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 torque compensation gain (n63
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 compensation gain. In these cases, set the V/f pattern (n09 to n15).
