Vector Speed and Torque Control set-up (P300 = 4 or 5)
In Volts per Hz mode the drive linearly increases output voltage as a direct function of the drive’s output frequency by the
slopeofthelinedenedbyP165(basevoltage)andP167(basefrequency).Invectormodethedrivedevelopsamathematic
model of the motor to determine the phase angle of the stator current components to more accurately regulate speed for
dynamic applications and to provide a method for torque control.
NOTE: If P300 = 4 or 5, a motor auto-calibration must be carried out. Ensure motor nameplate
