180 ACE-tronics G9 ASD Installation and Operation Manual
Cooling Fan Control
Program Protection Special Protection Parameters
This parameter sets the cooling fan run-time command.
Settings:
Automatic
Always On
Direct Access Number — F620
Parameter Type — Selection List
Factory Default — Always On
Changeable During Run — Yes
Bearing Greaser (Alarm) Time
Program Protection Special Protection Parameters
This parameter Enables/Disables the Maintenance Timer Alarm. The timer
sets a run-time value in hours that, once exceeded, initiates the Maintenance
Timer Alarm.
This setting, in conjunction with the setting of F489, may also affect the
commanded speed of the motor by providing a value for the Bearing Greaser
Speed Multiplier, if so configured.
A discrete output contactor may be set to Total-Operation-Hours Alarm to
control ancillary equipment (e.g., engage a brake) upon activation of the
discrete output contactor.
This feature is disabled by setting this parameter to Zero.
See Table 10 on pg. 242 for additional information on output terminal
selections.
Direct Access Number — F621
Parameter Type — Numerical
Factory Default — 0
Changeable During Run — Yes
Minimum — 0
Maximum — 65535
Units — Hour
Abnormal Speed Detection Time
Program Protection Abnormal Speed
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 — 1.00
Changeable During Run — Yes
Minimum — 0.01
Maximum — 100.00
Units — Seconds
Over-Speed Detection Frequency Upper Band
Program Protection Abnormal Speed
