–150: the bigger the coefficient, the bigger
the braking strength.
This VFD can slow down the motor by
increasing the magnetic flux. The energy
generated by the motor during braking can be
transformed 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.
The cooling is better. 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 process PID control.
The function code determines the target
reference channel during the PID process.
