Abnormal Speed Detection Filter Time
Program
Protection Parameters
⇒
This parameter sets the time that an overspeed condition must exist to cause a
trip.
Overspeed Detection Frequency Range
Program
⇒
Protection Parameters
This parameter sets the upper level of the Base Frequency range that, once
exceeded, will cause an Overspeed Detected alert.
Speed Drop Detection Frequency Range
Program
⇒
Protection Parameters
This parameter sets the lower level of the Base Frequency range that, once
exceeded, will cause a Speed Drop Detected alert.
Overvoltage Stall Level (fast)
Program
Protection Parameters
⇒
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 drive 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.
