5.2.1
Set the control method.
V/F control, Advanced magnetic flux vector control, and PM motor control are the control methods available for selection.
When using an IPM motor MM-EFS or MM-THE4, simply performing the motor parameter initialization (PM parameter
initialization or IPM initialization) enables PM motor control.
• The PM motor test operation can be performed by setting Pr.800 Control method selection.

*1 For the FR-F820-02330(55K) or lower and FR-F840-01160(55K) or lower.
*2 For the FR-F820-03160(75K) or higher and FR-F840-01800(75K) or higher.
*3 The initial value differs according to the inverter's voltage class (200/400 V class).
*4 When the IPM motor MM-EFS or MM-THE4 is selected in Pr.71 Applied motor, the rated frequency of the MM-EFS or MM-THE4 is used. When
a PM motor other than the MM-EFS or MM-THE4 is selected in Pr.71, 75 Hz (for the motor capacity of 15 kW or lower) or 100 Hz (for 18.5 kW
or higher) is used.
 Setting the motor capacity and the number of motor poles (Pr.80, Pr.81)
• Motor specifications (the motor capacity and the number of motor poles) must be set to select Advanced magnetic flux
vector control or PM motor control.
• Set the motor capacity (kW) in Pr.80 Motor capacity and set the number of motor poles in Pr.81 Number of motor poles.
NOTE
• Setting the number of motor poles in Pr.81 automatically changes the setting of Pr.144 Speed setting switchover. (Refer to
page
 Selecting the fast-response operation (Pr.800 = "109 or 110")
• Setting Pr.800 = "109 to 110" selects the fast-response operation. The fast-response operation is available during PM
motor control.

NOTE
• Refer to
• The inverter overload trip (E.THT) is more likely to occur when fast-response operation is set.
