5.5.4 Energy saving operation
Energy can be saved by decreasing the output voltage of the inverter in
steady-state under a light load condition.
Do not use the energy-saving function in normal situation.

Level
• S3.02 sets the minimum frequency for the effective energy saving
operation
• Energy-saving command is enabled when output frequency is higher
than the energy-saving frequency and motor speed is within the "speed
match" range or energy saving command is triggered from a external
input terminal.
