Description
Default

b5-84
(31B2)
RUN
Feedback Loss Loss Of
Prime Lvl
Sets the level at which the drive will detect Loss of Prime in the pump.
0.0 A
(0.0 - 1000.0 A)
Note:
•
A Loss of Prime condition occurs when the measured quantity set by
Y1-18 [Prime Loss Detection Method]
decreases to this level for the
time set in
Y1-20 [Loss of Prime Time]
and the output frequency is at the
Y4-02 [Pre-Charge Frequency]
level.
•
The drive will respond to the Loss of Prime condition as specified by
Y1-22 [Loss of Prime Selection]
.
•
Display unit and scaling are dependent on System Units.

When
b5-82 = 3 [Feedback Loss 4
~
20mA Detect Sel = Run At b5-83]
and the Feedback signal is
lost, the drive will run at the
b5-83 [Feedback Loss Goto Frequency]
speed for this length of time,
after which the drive will fault on
FDBKL [WIRE Break]
.
0 s
(0 - 6000 s)
Note:
Set this parameter to 0.0 s to disable the function.

RUN
Feedback Loss Start Delay
When you initiate an AUTO Run command, the drive will wait for this length of time before it will
fault on
FDBKL [WIRE Break]
or use parameter
b5-83 [Feedback Loss Goto Frequency]
.
0.0 s
(0.0 - 120.0 s)

b8: Energy Saving
Energy-saving control operates the motor at its most efficient level to improve overall system operating efficiency.
When you use V/f Control, set these parameters:
•
b8-01 [Energy Saving Control Selection]
•
b8-04 [Energy Saving Coefficient Value]
•
b8-05 [Power Detection Filter Time]
•
b8-06 [Search Operation Voltage Limit]
Note:
•
Energy-saving control is not appropriate for applications with sudden changes in the load or applications driving heavy loads.
•
Energy-saving control maximizes operation based on precise motor data set to the drive. Do Auto-Tuning and enter the correct information
about the motor before you use Energy-saving control.
