motor during braking can be converted into heat
energy by increasing the magnetic flux.
The VFD monitors the state of the motor
continuously even during the magnetic flux period.
So the magnetic flux can be used in the motor stop,
as well as to change the rotation speed of the motor.
Its other advantages are:
Brake immediately after the stop command. It does
not need to wait the magnetic flux weaken.
Better cooling for motors. The current of the stator
other than the rotor increases during magnetic flux
braking, while the cooling of the stator is more
effective than the rotor.

When the frequency command selection (P00.06,
P00. 07) is 7 or the voltage setting channel selection
(P04.27) is 6, the running mode of the VFD is
procedure PID controlled.
The parameter determines the target given channel
during the PID procures.
