100–150: A greater
greater braking strength.
The VFD can quickly slow down the motor by
increasing the magnetic flux. The energy
generated by the motor during braking can
be transformed
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 for
motor stop, as well as for motor rotation
speed change. Its other advantages include:
Braking is performed immediately after the
stop command is given. The braking can be
started without waiting for magnetic flux
weakening.
The cooling is better. The current of the stator
other than the
magnetic flux braking, while the cooling of
the stator is more effective than the rotor.
This function code is used to adjust the
displayed current on the AC input side.
Setting range: 0.00–1.00
When the frequency command selection
(P00.06, P00.07) is 7 or the voltage setting
channel selection (P04.27) is 6, the VFD is
process PID controlled.
The function code determines the target
given channel during the PID process.
