Figure 3‑43 Overvoltage stall suppression action
Para. No. Name
Default
Value Range Description
F3‑22
V/f overvoltage
stall suppression
action voltage
770.0 V
200.0 V to
2000.0 V
The function of F3‑22 is similar
to that of F9‑04.
F3‑23
V/f overvoltage
stall suppression
1
0: Disabled
1: Enabled
0: Disabled
1: Enabled (default)
F3‑24
Frequency gain
for V/f
overvoltage stall
suppression
30 0 to 100
Increasing F3‑24 will improve
the bus voltage control effect,
but the output frequency will
fluctuate. If the output
frequency fluctuates greatly,
reduce F3‑24 as appropriate.
F3‑25
Voltage gain for V/
f overvoltage stall
suppression
30 0 to 100
This parameter is used to
suppress the bus voltage.
Increasing the parameter
value reduces the overshoot
of the bus voltage.
F3‑26
Frequency rise
threshold during
overvoltage stall
suppression
5 Hz 0 Hz to 50 Hz
The running frequency may
increase when overvoltage
stall suppression is enabled.
This parameter limits the rise
of the running frequency.
F3‑10
V/f overexcitation
gain
64 0 to 200
A larger overexcitation gain
indicates better suppression
effect. When a braking
resistor, braking unit, or
energy feedback unit is used,
set this parameter to 0.
Otherwise, overcurrent may
occur during operation.
F3‑11
V/f oscillation
suppression gain
Model
depend
ent
0 to 100
A larger oscillation gain
indicates better suppression
effect.
