W7 ASD Installation and Operation Manual 95
Overvoltage Stall Level (fast)
Program Protection Settings Overvoltage Stall Level (fast)
This parameter sets the upper DC bus voltage threshold that, once exceeded,
will cause an Overvoltage Stall. An Overvoltage Stall increases the output
frequency of the ASD during deceleration for a specified time in an attempt to
prevent an Overvoltage Trip.
If the overvoltage condition persists for over 250 µS, an Overvoltage Trip will
be incurred.
Note: This feature may increase deceleration times.
