Auto energy saving operation
This feature controls the terminal voltage of the motor automatically to minimize the
motor power loss. (Note that this feature may not be effective depending upon the
motor characteristics. Check the characteristics before using this feature.)
The inverter enables this feature for constant speed operation only. During accel-
eration and deceleration, the inverter will run with manual or automatic torque boost,
depending on function code F37. If auto energy saving operation is enabled, the
response to a change in motor speed may be slow. Do not use this feature for a
system that requires quick acceleration and deceleration.
When the base frequency is 60 Hz or lower, use the auto energy saving
operation. If it is higher than 60 Hz, the decreased or no effect of the auto
energy saving operation may be brought about.
The auto energy saving operation is designed for use with the frequency
lower than the base frequency. If the frequency becomes higher than the
base frequency, the auto energy saving operation will be invalid.
For the auto energy saving function, which is related to the motor char-
acteristics, you need to consistently set the voltage at the base frequency
(F05) and motor parameters P02, P03 and P99 appropriately for the motor
rating and characteristics.
Given below are proper setting examples with the combination of F09 and F37.
