YASKAWA VS MINI J7 Series Instruction Manual page 60

When operating with frequency larger than 60Hz/50Hz, change only maximum 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 J7 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.
Output voltage
Operation
Normally, no adjustment is necessary for torque compensation gain (n63 factory
setting: 1.0). When wiring distance between the inverter and motor is long or when
motor generates vibration, change the automatic torque compensation gain. In these
cases, it may also be beneficial to adjust the V/f pattern (n09 to n15).
