Changing The Control Method - Mitsubishi Electric FR-A820-00046 Instruction Manual

Control method
5.2.2

Changing the control method

Set the control method and control mode.
V/F control, Advanced magnetic flux vector control, Real sensorless vector control, Vector control,
and PM sensorless vector control are the control methods available for selection.
The control modes are speed control, torque control, and position control. These are set when se-
lecting Advanced magnetic flux vector control, Real sensorless vector control, Vector control, and PM
sensorless vector control. Select a control mode from speed control mode, torque control mode and
position control mode under Real sensorless vector control or vector control. The initial setting is V/
F control.
When using an IPM motor MM-CF, simply performing the IPM parameter initialization enables the PM
sensorless vector control and selects the speed control and position control.
● Select a control method and control mode by using Pr. 800 (Pr. 451) "Control method selection".
● The control mode can be switched using the mode switching signal (MC).

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.
