When torque boost is set to 0.0%, the VFD
uses
automatic torque boost.
Torque boost cut
-off threshold: Below this
frequency threshold, torque boost is valid;
exceeding this threshold will invalidate torque
boost.

When
P04.00=1 (multi-dot V/F curve), you can
set the V/F curve through
P04.03±P04.08.
The V/F curve is generally set according to the
load characteristics of the motor.
Note: V1 < V2 < V3, f1 < f2 < f3. Too high
voltage for low frequency will cause motor
overheat or damage and cause VFD
overcurrent stall or overcurrent protection.
