Note:
The function to automatically reduce the stall prevention level does not operate when
L3-01 = 3 [Stall Prevention during Accel = Current
Limit Method]

Stall Prevention during
Decel
Sets the method that the drive will use to prevent overvoltage faults when decelerating.
1
(0 - 4)
Stall Prevention during deceleration controls the deceleration as specified by the DC bus voltage and does not let high
inertia or fast deceleration cause
ov [Overvoltage]
faults.
0 : Disabled
The drive decelerates as specified by the deceleration time. If the deceleration time is too short, the drive can detect an
ov
fault.
1 : General Purpose
The drive decelerates as specified by the deceleration time. When the DC bus voltage is more than the Stall
Prevention level, the drive stops deceleration until the DC bus voltage is less than the Stall Prevention Level. The
drive then starts to decelerate at the set deceleration time. Frequent use of Stall Prevention will help prevent
ov
faults
when the deceleration time is shorter than the drive can usually accept.
Note:
The Decel Stall Prevention function will increase the deceleration time to stop and the deceleration time will be longer than the setting.
The input voltage setting of
E1-01 [Input AC Supply Voltage]
sets the DC bus voltage level for Stall Prevention.
