b8 Ener y Sa in Coe icient alue ( / )
Fine tunes Energy Saving control. Adjust this setting while viewing the output power monitor (U1-08) and running the drive
with a light load.
A low setting results in less output voltage and less energy consumption. If the value is set too low the motor may stall. The
default setting depends on the capacity of the drive.
No
b8-04
The default value changes if the motor rated capacity set to E2-11 is changed. The Energy Saving coefficient is set automatically when
Note:
Auto-Tuning for Energy Saving is performed.
b8 Po er Detection Filter ime ( / )
Determines how often in milliseconds the output power is measured. The Energy Saving function continuously searches out
the lowest output voltage to achieve minimum output power.
Reducing this setting increases the response time. If the filter time is too short, the motor may become unstable with a lighter
load.
No
b8-05
b8 Searc Operation olta e Limit ( / )
Sets the voltage limit for the Speed Search optimal output voltage detection as a percentage of the maximum output voltage.
The drive will keep the output voltage above this level during the search operation to prevent motor stalling.
If set too low, the motor may stall when the load is suddenly increased. Disabled when set to 0. Setting this value to 0 does not disable
