Program Protection
This parameter sets the cooling fan run-time command.
Settings:
0 — Automatic
1 — Always On
Direct Access Number — F620
Parameter Type — Selection List
Factory Default — Automatic
Changeable During Run — Yes
Run-Time Alarm Setting
Program Protection
This parameter sets a run-time value that, once exceeded, closes a discrete output
contact. The output signal may be used to control external equipment or used to
engage a brake.
Associate the Total-Operation-Hours Alarm setting of Table 7 on pg. 190 to a
discrete output contactor.
Note: The time displayed is 1/10th of the actual time (0.1 hr. = 1.0 hr.).
Direct Access Number — F621
Parameter Type — Numerical
Factory Default — 610.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — 999.9
Units — Hours (X 10)
Abnormal Speed Time
Program Protection
This parameter sets the time that an overspeed condition (speed drifts outside of
the F623 and F624 range) 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

Program Protection
This parameter sets the upper level of the Abnormal Speed range that, once
exceeded, will cause an Overspeed Detected alert.
This parameter functions in conjunction with the settings of F622 and F624.
Direct Access Number — F623
Parameter Type — Numerical
Factory Default — 0.0 (Disabled)
Changeable During Run — Yes
Minimum — 0.0 (Disabled)
Maximum — 30.00
Units — Hz
Abnormal Speed Lower Band
Program Protection
This parameter sets the lower level of the Abnormal Speed 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 (Disabled)
Changeable During Run — Yes
