The inverter operates as a voltage source, generating frequency and voltage values according to that curve. It is possible to adjust this curve to standard 50 Hz or 60 Hz motors or to special ones through the adjustable V/f curve.

Scalar Control (V/f) 9.4 V/F DC VOLTAGE LIMITATION [27] There are two functions in the inverter for limiting the DC link voltage during the motor braking. They act limiting the braking torque and power, avoiding therefore the tripping of the inverter by overvoltage (F022). The overvoltage on the DC link is more common when a load with high inertia is driven or when a short deceleration time is programmed.

Scalar Control (V/f) Description: It is the actuation level of the DC link voltage limitation function for the V/f mode. Setting of P0151 value: a) The P0151 factory setting leaves inactive the DC link voltage limitation function for the V/f mode. In order to activate it, one must reduce the value of P0151 as suggested in the Table 9.2 on page 9-13.
Page 108 Scalar Control (V/f) The energy saving function reduces the motor losses when it is running with loads significantly below the rated load. The efficiency is increased by reducing the motor flux, which is kept saturated for any load value. The function is active when the applied load is smaller than the value set in P0588, and the motor effective speed is higher than the value set in P0589.

In the DC braking case, only the losses in the motor rotor are used to dissipate the energy stored as the mechanic load inertia, rejecting the total friction losses.
