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 F623
and F624.
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 F622
and F624.
Direct Access Number —
F623
Parameter Type — Numerical
Factory Default — 0.00 (Dis-
abled)
Changeable During Run — Yes
Minimum — 0.00 (Disabled)
Maximum — (ASD-Dependent)
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 F622
and F623.
Direct Access Number —
F624
Parameter Type — Numerical
Factory Default — 0.00 (Dis-
abled)
Changeable During Run — Yes
Minimum — 0.00 (Disabled)
Maximum — (ASD-Dependent)
Units — Hz
Under-Voltage Detection Level
Program Protection Under-Voltage/Ridethrough
This parameter sets the voltage threshold level that is used
as a setpoint for under-voltage tripping.
This function is enabled at F627.
Direct Access Number —
F625
Parameter Type — Numerical
Factory Default — 60
Changeable During Run — No
Minimum — (ASD-Dependent)
Maximum — (ASD-Dependent)
Units — %
