100–150: The bigger the coefficient, the stronger
the braking is.
This VFD is used to increase the magnetic flux to
decelerate the motor. The energy generated by
the motor during braking can be converter 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.
