b8-04: Energy Saving Coefficient Value (V/f Control)
Parameter b8-04 is used to fine tune the Energy Saving control. The default setting depends on the capacity of the drive.
The value can be optimized in small amounts while viewing the output power monitor (U1-08) and running the drive.
A smaller value results in less output voltage and less energy consumption, but a too small value will cause the motor to
stall.

b8-04 Energy Saving Coefficient Value 0.00 to 655.00
Determined by
C6-01, E2-11, and
o2-04
Note: This default value changes if the motor rated capacity set to E2-11 is changed. The Energy Saving coefficient is set automatically when
Auto-Tuning for Energy Saving is performed (Refer to Auto-Tuning on page 87).
n
b8-05: Power Detection Filter Time (V/f Control only)
The Energy Saving function continuously searches out the lowest output voltage in order to achieve minimum output
power. Parameter b8-05 determines how often the output power is measured and the output voltage is adjusted.

b8-06: Search Operation Voltage Limit (V/f Control only)
Sets the voltage limit for the optimal output voltage detection of Speed Search as a percentage of the maximum output
voltage. During the search operation the drive will keep the output voltage above this level to prevent motor stalling.
Note: If set too low, the motor may stall with a sudden increase to the load. Disabled when b8-06 = 0. Setting this value to 0 does not disable
Energy Saving.
