L3 Stall Prevention/Current Limit
This function automatically adjusts the deceleration rates in order to continue operation without tripping the
inverter.
L3-01 Over-voltage Protection (Stall Prevention During Deceleration)
If deceleration times are set too short for load conditions, the inverter automatically extends the deceleration time
according to the main circuit DC bus voltage level. When using an optional braking resistor for the VS-616PS5, set
parameter L3-01 to"0".
Setting Explanation
VS-616PS5 Installation & Quick Start Manual
Stall prevention during deceleration is disabled. An exces-

sively short deceleration time will generate an overvoltage
fault (OV), and the motor will coast.
Stall prevention during deceleration is enabled (factory
1
default).
The DC bus voltage level is monitored, and the deceleration
rate is automatically extended to prevent an overvoltage
condition. This deceleration time may be longer than the
set value (C1-02).
