5.2.1 Changing the control method
Set the control method.
V/F control, Advanced magnetic flux vector control, and PM motor control are the control methods available for selection.
• The PM motor test operation can be performed by setting Pr.800 Control method selection.

*2 For the FR-F860-01080 or higher.
 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 changes the Pr.144 Speed setting switchover setting automatically. (Refer
to page 272.)
 PM motor control test operation (Pr.800 = "9")
• Test operation in the speed control is available without connecting a motor. 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
the terminal AM or CA.
NOTE
• 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.

Description
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.
V/F control
Set the number of motor poles.
V/F control
Set the rated motor voltage (V).
Set the rated motor frequency (Hz).
The setting value of Pr.3 Base frequency is used.
PM motor test operation (Motor is not driven even if
it is connected.)
Normal operation (Motor can be driven.)
PM motor test operation (Motor is not
driven even if it is connected.)
Normal operation (Motor can be driven.)
