Abnormal Speed Detection Time
Program
Protection
Abnormal Speed Settings
This parameter sets the time that an over-speed condition must exist to cause a
trip.
This parameter functions in conjunction with the settings of
.
Direct Access Number — F622
Parameter Type —
Numerical
Factory Default —
0.01
Changeable During Run —
Yes
Minimum — 0.01
Maximum — 100.00
Units — Seconds
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
.
Direct Access Number — F623
Parameter Type —
Numerical
Factory Default —
0.00 (Disabled)
Changeable During Run —
Yes
Minimum — 0.0 (Disabled)
Maximum — 30.00
Units — Hz
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
.
Direct Access Number — F624
Parameter Type —
Numerical
Factory Default —
0.00 (Disabled)
Changeable During Run —
Yes
Minimum — 0.00 (Disabled)
Maximum — 30.00
Units — Hz
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 ASD 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.
Note:
This parameter setting may increase deceleration times.
Direct Access Number — F626
Parameter Type —
Numerical
Factory Default —
(ASD-Dependent)
Changeable During Run —
Yes
Minimum — 100
Maximum — 150
Units — %
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
setting.
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
Direct Access Number — F627
Parameter Type —

Factory Default —
Disabled
Changeable During Run —
No
