FA.01
Motor overload protection curve
coefficient
The motor overload protection factor is the
percentage of the rated current value of the
motor to the rated output current value of the
VFD.
30%-110% 100%
FA.02 Undervoltage protection level
This power parameter specifies the allowable
lower limit voltage of the DC bus when the
inverter is working normally.

voltage for overvoltage stall protection
350-380V
660-760V
375/660V
FA.05 Current limit level
The current limit level defines the current
threshold value of the automatic current limit
action, and its set value is a percentage relative
to the rated current of the VFD.

0-2 0
FA.08 Overload pre-alarm level
The current threshold of the VFD overload
pre-alarm action, and its set value is a
percentage relative to the rated current of the
inverter.
120-150% 120%
FA.09 Overload pre-alarm delay
The delay time between the VFD output current
continuously greater than the overload pre-alarm
level amplitude (FA.08) and the output of the
overload pre-alarm signal.
0.0-15.0s 5.0s

Oscillation suppression
coefficient
In general, when the motor oscillates, increase
the oscillation suppression coefficient.
