(Virtual Linear Pump) Low Suction/No-Flow Cut Off Fault
Disposition
Program Virtual Linear Pump Low Suction/No-Flow Cut Off
This parameter is used in conjunction with the setting of F483.
If On (Physical Switch) or On (Electronic Switch) is selected at F483, then
this parameter selection sets the disposition of the system in the event of a Low
Suction/No-Flow Cut Off condition that exists for the duration of the
F484
setting.
If Off is selected at F483, then this parameter selection is ignored.
Settings:
0 — Trip
1 — Alarm
2 — Alarm and Restart at F484 Interval
Direct Access Number — F450
Parameter Type — Selection List
Factory Default — Trip
Changeable During Run — Yes
Accel/Decel Operation After Torque Limit
Program Torque Torque Limit Settings
In a Crane/Hoist application that is operating using a mechanical brake, this
parameter is used to minimize the delay between the brake release and the
output torque reaching a level that can sustain the load.
This setting may reference time or the operating speed of the motor.
Settings:
0 — In Sync with Accel/Decel
1 — In Sync with Minimum Time
Direct Access Number — F451
Parameter Type — Selection List
Factory Default — In Sync with Accel/
Decel
Changeable During Run — Yes
Power Running Stall Continuous Trip Detection Time
Program Protection Stall
This parameter is used to extend the Over-Voltage Stall (F305) and the Over-
Current Stall (F017) time settings.
Direct Access Number — F452
