Use auto-energy saving only where the base frequency is 60 Hz or lower.
If the base frequency is higher than 60 Hz, then you may get little or no
energy saving effect.
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 examples of proper setting in combination with F09 and F37.
