Settings
 When energy-saving is enabled, the motor acceleration and deceleration operate with full
voltage. During constant speed operation, it automatically calculates the best voltage value
according to the load power. This function is not suitable for fluctuating loads or loads which are
nearly full during operation.
 When the output frequency is constant (that is, constant operation), the output voltage
decreases automatically as the load decreases. Therefore, the drive operates with minimum
multiplication of voltage and current (electric power).
 VF and SVC mode:
Steady-speed: When output is light load, entry into the energy saving mode after 5 seconds.
Return: When the drive is continuously adding loads, or in non-steady speed status.
0: Disable
1: Enable
