6 Parameter Table
No. Name
0: Disabled. Deceleration at the active
deceleration rate. An ov fault may occur.
1: General purpose. Deceleration is
paused when the DC bus voltage exceeds
the Stall Prevention level.
2: Intelligent. Decelerate as fast as possible
while avoiding ov faults.
Stall 3: Stall Prevention with braking resistor.
Prevention Stall Prevention during deceleration is
L3-04 Selection enabled in coordination with dynamic
during braking.
Deceleration 4: Overexcitation Deceleration. Decelerates
while increasing the motor flux.
5: Overexcitation Deceleration 2. Adjust the
deceleration rate according to the DC bus
voltage.
6: Enabled. Decelerates adjusting the
deceleration rate according to the output
current and the DC bus voltage.
0: Disabled. Drive runs at a set frequency. A
heavy load may cause speed loss.
Stall 1: Decel time 1. Uses the deceleration
Prevention time set to C1-02 while Stall Prevention is
L3-05
Selection performed.
during Run 2: Decel time 2. Uses the deceleration time
set to C1-04 while Stall Prevention is
performed.
Stall
Prevention Enabled when L3-05 is set to 1 or 2. 100%
