The reference for this value is the motor
overload current. When the inverter
detects that the output current reaches
(F9-02)× motor overload current and lasts
time as specified by the reverse time-lag
curve, it outputs pre-warning signal from
DO or relay.

range
0 to 100 (no

voltage)
It adjusts the inverter ’s capacity in
suppressing the stall over voltage. The
bigger the value is, the stronger the
suppressing capacity is.
For the load with small inertia, the value
should be small. Otherwise, the dynamic
response of the system will be slow.
For the load with lar ge i nert ia, th e
value should be large. Otherwise, the
suppressing result will be poor, and over
voltage fault may occur.

Select the protection point for function
of st all ove r voltage. When th e
value is exceeded, the inverter starts
executing the protection function for
stall over voltage.
