220V:
180~280V
200V
380V:
330~480V
350V
Depending
on model
This function code specifies the lower limit of DC bus
voltage when the driver operates normally.
Notice:
When the network voltage is low, the output torque of
motor will decrease. In conditions of constant power
load and constant torque load, the low network
voltage will increase the input an output current of
VFD, so as to lower the reliability of VFD operation.
Therefore the VFD need to run in derated capacity
when the network voltage is quite low for long term.
FA.04
Overvoltage limit level
220V:
350~390V
370V
380V:
550~780V
660V
Depending
on
model
This parameter defines the action voltage of stall
overvoltage protection.
FA.05
voltage limit factor in decelerating
0~100 0: overvoltage
stall protection invalid
Depending on
model
During decelerating, the larger of this value, the
stronger of the overvoltage suppressing ability.
FA.06
Current limit threshold(only valid in V/F
mode)
G type: 80%~200%*VFD
rated current 160%
P type: 80%~200%*VFD
rated current 120%
Depending on
model
This parameter defines auto current limiting threshold,
and the set value is the percentage relative to the
rated current of VFD.
Notice:
In the normal VF mode, FA.06 is used for amplitude
limiting during accelerating or constant speed running;
in Vector VF mode, FA.06 is used for amplitude limiting
during accelerating, and no such limit process during
constant speed running; in vector mode, the
amplitude limit during constant speed running is only
related to F4.20~F4.21.
FA.07
Current limiting in field weakening region
0~1
0
0: limited by current limiting threshold of FA.06.
When output frequency is within 50Hz, FA.06 is
used for amplitude limiting.
1: limited based on corrected current from FA.06
When output frequency is above 50Hz, amplitude
