Changing The Control Method - Mitsubishi Electric FR-F800 Instruction Manual

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.

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.

Control method
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.)
