Abnormal Speed Detection Time
Program Protection Abnormal Speed Settings
This parameter sets the time that an overspeed condition must exist to cause a
trip.
This parameter functions in conjunction with the settings of
Over-Speed Detection Frequency Upper Band
Program Protection Abnormal Speed Settings
This parameter sets the upper level of the Base Frequency range that, once
exceeded, will cause an Over-Speed Detected alert.
This parameter functions in conjunction with the settings of
Over-Speed Detection Frequency Lower Band
Program Protection Abnormal Speed Settings
This parameter sets the lower level of the Base Frequency range that, once the
output speed falls below this setting, will cause a Speed Drop Detected alert.
This parameter functions in conjunction with the settings of
Over-Voltage Limit Operation Level
Program Protection Stall
This parameter sets the upper DC bus voltage threshold that, once exceeded,
will cause an Over-Voltage Stall. An Over-Voltage Stall increases the output
frequency of the drive during deceleration for a specified time in an attempt to
prevent an Over-Voltage Trip.
If the over-voltage condition persists for over 4 mS, an Over-Voltage Trip will
be incurred.
This parameter is enabled at F305.
Note: This parameter setting may increase deceleration times.
Under-Voltage Trip
Program Protection Under-Voltage/Ridethrough
This parameter Enables/Disables the Under-Voltage Trip function.
With this parameter Enabled, the ASD will trip if the under-voltage condition
persists for a time greater than the
A user-selected contact may be actuated if so configured.
If Disabled the ASD will stop and not trip; the FL contact is not activated.
Settings:
0 — Disabled
1 — Enabled
