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.

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 - 6000 s)
Note:
Set this parameter to 0.0 s to disable the function.

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] .

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.

Energy Saving Coefficient
Value
Sets the Energy-saving control coefficient to maintain maximum motor efficiency. The default setting
is for Yaskawa motors.
Determined by E2-11 and
o2-04
(0.00 - 655.00)
When you use a motor from a different manufacturer, increase the setting value in 5% increments to find the
minimum value for
U1-08 [Output Power] at light loads.
When you decrease the setting value, it decreases the output voltage and decreases power consumption. If the setting
value is too low, the motor will stall.
