P12.09 Torque boost

Automatic torque boost
When P12.09=0=Automatic torque boost,inverter will automatically compensate output voltage to improve
torque in low frequency as per actual load ,it is useful for linear VF curve

Manual torque boost

When P12.09 not
value=p12.09*motor stator resistance *rated excitation current,,increasing value will be gradully decreased
as frequency increase ,if higher than 50% of motor rated frequency,increasing value will be zero

Notice:manual torque boost is useful to linear and power curve
