F442
Regenerative Braking Torque Limit 1
Program  Torque Torque Limit Settings
This parameter determines the source of the Regenerative Torque Limit
control signal.
If F443 is selected, the value set at
Limit setting.
Settings:
1 — V/I
2 — RR
3 — RX
4 — F443 (Setting)
Regenerative Braking Torque Limit 1 Level
Program Torque Torque Limit Settings
This parameter provides a value to be used as the Regeneration Torque
Limit 1 if F443 is selected at parameter F442.
Set this parameter to 250% to disable this function.
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 parameter F483.
If On (Physical Switch) or On (Electronic Switch) is selected at parameter
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 parameter F484 setting.
If Off is selected at parameter F483, then this parameter selection is ignored.
Settings:
0 — Trip
1 — Alarm
2 — Alarm (auto-restart)
Constant Output Zone Torque Limit
Program Torque Torque Limit Settings
This parameter is used to select if either Constant Torque is applied to the load
as selected (selection 1) or if the ASD is allowed to use an over-voltage
condition to support a torque requirement at the load that exceeds that of the
Constant Torque operation setting during an active over-speed (selection 0).
Settings:
0 — Constant Output Limit
1 — Constant Torque Limit
