power
consumption
This parameter is used to set the original value of the
power consumption.
The original value of the power consumption =P08.48 x
1000 + P08.49
Setting range of P08.48: 0
–59999 kWh (k)
Setting range of P08.49:0.0
–999.9 kWh

Magnetic flux
braking
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 the 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.
