P08.48
High bit of

consumption
value
This parameter is used to set the original value of
the power consumption.
The original value of the power consumption
=(P08.48×1000+ P08.49) kWh
Setting range of P08.48: 0

Flux brake
coefficient
This function code is used to enable magnetic
flux.
0: Invalid.
100
– 150: the bigger the coefficient, the bigger
the braking strength.
This VFD can slow down the motor by increasing
the magnetic flux. The energy generated by the
motor during braking can be transformed into
heat energy by increasing the magnetic flux.
The VFD monitors the state of the motor
continuously even during magnetic flux period.
So the magnetic flux can be used in the motor
stop, as well as to change the rotation speed of
the motor. Its other advantages are:
Brake immediately after the stop command. It
does not need to wait the magnetic flux weaken.
The cooling is better. The current of the stator
other than the rotor increases during magnetic
flux braking, while the cooling of the stator is
more effective than the rotor.
