Control method Parameters
5 - 70
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 5-73.)
[PM] on the operation panel (FR-DU08) is on when the PM sensorless vector control is set.
Example

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 5-71.)
