Control method Parameters
5 - 38
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.
When using an IPM motor MM-EFS or MM-THE4, simply performing the IPM parameter initialization
enables the PM motor control.
●
The PM motor test operation can be performed by setting Pr. 800 "Control method selection".
For the FR-F820-02330(55K) or lower, and the FR-F840-01160(55K) or lower.
For the FR-F820-03160(75K) or higher and the FR-F840-01800(75K) or higher.
The initial value differs according to the voltage class. (200V class/400V class)
When the IPM motor MM-EFS or MM-THE4 is selected by 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 by Pr. 71, 75 Hz (for the motor capacity 15 kW or lower) or 100 Hz (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".
