Parameters Control method
FR-A800 5 - 75
5.2.4 Selecting the PM sensorless vector control
Selecting the PM sensorless vector control by performing parameter initialization on the
operation panel (
)
NOTE The parameters required to drive an MM-CF IPM motor are automatically changed as a batch.
(Refer to page 5-78.)
[PM] on the operation panel (FR-DU08) is on when the PM sensorless vector control is set.
Example Operation example: Initialize the parameter settings for an MM-CF IPM motor by selecting IPM
parameter initialization on the operation panel.
Operation
Turning ON the power of the inverter
The monitor display turns ON.
Changing the operation mode
Press to choose the PU operation mode.
[PU] indicator turns ON.
Parameter setting mode
Press to choose the parameter setting mode.
[PRM] indicator turns ON.

Setting Description
0 Parameter settings for an induction motor
3003 Parameter settings for an IPM motor MM-CF (rotations per minute)
Tab. 5-26: Settings for the IPM parameter initialization
NOTES If parameters are initialized for a PM motor in the IPM initialization mode, the Pr. 998 "PM parame-
ter initialization" setting is automatically changed.
In the initial parameter setting, the capacity same as the inverter capacity is set in Pr. 80 "Motor
capacity". To use a motor capacity that is one rank lower than the inverter capacity, set Pr. 80
"Motor capacity" by selecting the mode on the operation panel.
To set a speed or to display monitored items in frequency, Pr. 998. (Refer to page 5-76.)
