This function code is used to enable flux braking
function.
0: Invalid
100–150: The larger the coefficient, the stronger
the braking intensity
The VFD enables motor to decelerate quickly by
increasing the motor flux which converts energy
generated during braking into thermal energy.
The VFD 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.
This function code is used to adjust the current
display value on the AC input side.
0.00–1.00
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.
0.00 Hz–P00.03 (Max. output frequency)
Note: This parameter is valid only for the torque
control mode.
