Stall Prevention Selection
During Decel
StallP Decel Sel
When using a braking resistor, use setting “0”. Setting “3” is used
in very specific applications.
0: Disabled - The Drive decelerates at the active deceleration rate.
If the load is too large or the deceleration time is too short, an
OV fault may occur.
1: General Purpose - The Drive decelerates at the active
deceleration rate, but if the main circuit DC bus voltage reaches
the stall prevention level (380/760 Vdc), deceleration will stop.
Deceleration will continue once the DC bus level drops below
the stall prevention level.
2: Intelligent - The active deceleration rate is ignored and the Drive
decelerates as fast as possible w/o hitting OV fault level.
Range: C1-02/10.
3: Stall Prevention w/ Braking Resistor
