Flux braking
This function code is used to enable flux braking
function.
0: Invalid
100–150: The larger the coefficient, the stronger the
brake intensity
The inverter enables motor to decelerate quickly by
increasing the motor flux which converts energy
generated during braking into thermal energy.
The inverter monitors motor state continuously even
during flux braking, thus flux braking can be applied
in motor stop or used to change motor speed. The
flux braking also carries the following advantages.
1) Brake immediately after sending stop command,
removing the need to wait for flux to attenuate.
2) Better cooling effect. During flux braking, the
stator current of the motor increases, while the rotor
current does not change, while the cooling effect of
stator is much more effective than that of the rotor.
