Description
0: Save when power off
1: Clear when power off
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: 0–59999
Setting range of P08.49: 0.0–999.9
This function code is used to enable magnetic flux.
0: Invalid.
100–150: The bigger the coefficient, the stronger
the braking is.
This VFD is used to increase the magnetic flux to
decelerate the motor. The energy generated by
the motor during braking can be converted 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.
Better cooling for motors. 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.
This function code is used to adjust the displayed
current of the AC input side.
Setting range: 0.00–1.00
Description
When the frequency command selection (P00.06,
P00.07) is 7 or the voltage setting channel
selection (P04.27) is 6, the running mode of the
VFD is procedure PID controlled.
