When operating with frequency larger than 60 Hz/50 Hz, change only
max. output frequency (n09).
Full-range Automatic Torque Boost
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 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 the 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).
