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

–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.

STO lock
0: STO alarm lock
Alarm-lock means STO alarm must be reset after
state restoration when STO occurs.
1: STO alarm unlock
Alarm-unlock means when STO occurs, after
state restoration, STO alarm will disappear
automatically.

When frequency command (P00.06, P00.07) is
set to 7, or channel of voltage setup (P04.27) is
set to 6, the inverter running mode is process PID
control.
