P9-03
Overvoltage stall gain
Default
0
Setting Range
0 (no stall overvoltage)–100
P9-04
Overvoltage stall protective voltage
Default
130%
Setting Range
120% - 150%
When the DC bus voltage exceeds the value of P9-04 (Overvoltage stall protective voltage)
during deceleration of the AC drive, the AC drive stops deceleration and keeps the present running
frequency. After the bus voltage declines, the AC drive continues to decelerate.
P9-03 (Overvoltage stall gain) is used to adjust the overvoltage suppression capacity of the AC
drive. The larger the value is, the greater the overvoltage suppression capacity will be in the
prerequisite of no overvoltage occurrence, set F9-03 to a small value.
For small-inertia load, the value should be small. Otherwise, the system dynamic response will
be slow. For large-inertia load, the value should be large. Otherwise, the suppression result will be
poor and an overvoltage fault may occur.
If the overvoltage stall gain is set to 0, the overvoltage stall function is disabled.
The overvoltage stall protective voltage setting 100% corresponds to the base values in the
following table:
