For theFR-A820-03160(55K) or lower, and theFR-A840-01800(55K)or lower.
For theFR-A820-03800(75K) or higher and theFR-A840-02160(75K)or higher.
The initial value differs according to the voltage class. (200V class/400V class)
When the IPM motor MM-CF is selected by Pr.71 Applied motor, the rated frequency of the MM-CF is used. When a PM motor other than the
MM-CF 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.
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 selecting 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).
