■ b5-84: Feedback Loss Loss Of Prime Lvl
No.
(Hex.)
Name Description
Default
(Range)
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.
■ b5-85: Feedback Loss GoTo Freq Timeout
No.
(Hex.)
Name Description

(Range)
b5-85
(31B3)
RUN
Feedback Loss GoTo Freq
Timeout
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.
■ b5-86: Feedback Loss Start Delay
No.
(Hex.)
Name Description
Default
(Range)
b5-86
(31B4)
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.
■ b8-01: Energy Saving Control Selection
