• When the SF-PR/SF-HR/SF-HRCA motor is used (Pr.71 = "40, 43, 44, 50, 53, 54, 70, 73, or 74") and "9999" is set in Pr.85/
Pr.86, the predetermined setting in the following table is applied.

The inverter will automatically perform energy saving operation without setting detailed parameters.
This control method is suitable for applications such as fans and pumps.

control selection
Energy saving operation (Pr.60 = "4")
• Setting Pr.60 = "4" will select the energy saving operation.
• With the energy saving operation, the inverter will automatically control the output voltage so the inverter output power
during the constant-speed operation will become minimal.
• Energy saving operation will be enabled under V/F control.
Optimum excitation control (Pr.60 = "9")
• Setting Pr.60 = "9" will select the Optimum excitation control.
• The Optimum excitation control is a control method to decide the output voltage by controlling the excitation current so the
efficiency of the motor is maximized.
• Optimum excitation control will be enabled under V/F control and Advanced magnetic flux vector control.
