4501 ENERGY OPTIMIZER OFF
Enables or disables the energy optimizer, which optimizes the ux so that the total energy consumption and motor noise level are reduced when the drive
operates below the nominal load. The total efciency (motor and drive) can be improved by 1…10% depending on load torque and speed.
