braking
This function code is used to enable magnetic flux braking.

100~150: The larger the coefficient is, the stronger the braking is.
This inverter can slow down the motor by increasing the magnetic flux. In this way, the energy generated
by the motor during braking can be transformed into heat energy.
The inverter monitors the state of the motor continuously even during the magnetic flux braking period.
So the magnetic flux braking can be used in the motor stop, as well as to change the rotating speed of the
motor. The other advantages are:
Brake immediately after the stop command. It does not need to wait until the magnetic flux weakens.
The cooling effect becomes better. The current of the stator other than that of the rotor increases during
magnetic flux braking, while the cooling of the stator is more effective than the cooling of the rotor.
