P3-03 Stall Prevention during Deceleration
The Stall Prevention function during deceleration controls the deceleration base on the main
circuit DC voltage, and use high inertia or rapid deceleration to prevent an ov (Overvoltage)
fault.
No. Name Setting Range Default
P3-03 Stall Prevention during Deceleration 0 to 1 1
0 : Disabled
The drive decelerates according to the set deceleration time. With high intertia loads or rapid
deceleration, an ov (Overvoltage) fault could be triggered. Therefore use braking options or
set this parameter to 1.
1 : Enabled
When the main circuit voltage exceeds the tall Prevention level during acceleration, the
deceleration pauses and hold the frequency. When the main circuit voltage falls below the Stall
Prevention level, the drive continues to decelerate using the set deceleration time. Stall
Prevention might be triggered repeatedly to prevent an overvoltage fault.
Stall Prevention might lengthen the total deceleration time until a completely stop. Therefore
install a braking option for applications such as conveyors.
The Stall Prevention function is illustrated below.
