Changing the control method and mode
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.
Number of motor
Rated motor voltage 200/400 V
For the FR-F820-02330(55K) or lower and FR-F840-01160(55K) or lower.
For the FR-F820-03160(75K) or higher and FR-F840-01800(75K) or higher.
The initial value differs according to the inverter's voltage class (200/400 V class).
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.
• Setting the number of motor poles in Pr.81 automatically changes the setting of Pr.144 Speed setting switchover. (Refer to
PM motor test operation (Pr.800 = "9")
• A test operation for speed control is available without connecting a motor to the inverter.
The speed calculation changes to track the speed command, and such speed changes can be checked on the operation
panel or by outputting it as analog signals to terminal FM/CA or AM.
• Since current is not detected and voltage is not output, monitors related to current and voltage such as output current and
output voltage, etc. and output signals do not function.
I/O signal status during the test operation
• During the test operation, the following signals are disabled.

By selecting a standard motor or constant-torque motor, the
thermal characteristic and motor constant of each motor are set.
Set the applied motor capacity.
Set the number of motor poles.
Set the rated motor voltage (V).
Set the rated motor frequency (Hz).
The setting value of Pr.3 Base frequency is used.
