Setting procedure of PM sensorless vector control (speed control)

This inverter is set for a general-purpose motor in the initial setting. Follow the following procedure
to change the setting for the PM sensorless vector control.
Driving an MM-CF IPM motor
Perform IPM parameter initialization. (Refer to page 5-75.)
As required for MM-CF
Perform offline auto tuning for a PM motor. (Refer to page 5-471.)
Fig. 5-12:
5 - 88
Set "3003 or 3103" in Pr. 998 "PM parameter initialization" or select "3003" in
settings).
Setting value "3003": parameter settings for MM-CF IPM motor (rotations per minute)
Setting value "3103": parameter settings for MM-CF IPM motor (frequencies)
Driving a PM motor other than MM-CF
Set the motor. (Pr. 9, Pr. 71, Pr. 80, Pr. 81, Pr. 83, Pr. 84 ) (Refer to page 5-451, page 5-471.)
Perform offline auto tuning for a PM motor. (Pr. 96) (Refer to page 5-471.)
Configure the initial setting for the PM sensorless vector control using Pr. 998.
(Refer to page 5-76.)
Set parameters such as the acceleration/deceleration time and
multi-speed setting.
Set parameters such as the acceleration/deceleration time
and multi-speed setting as required.
Set the operation command. (Refer to page 5-271.)
Select the start command and speed command.
Test run
Setting procedure of PM sensorless vector control (speed control)
Set "8093 (IPM motor other than MM-CF)" or "9093 (SPM motor)" in
Pr. 71 "Applied motor". Set Pr. 9 "Rated motor current", Pr. 80 "Motor
capacity", Pr. 81 "Number of motor poles", Pr. 83 "Rated motor
voltage, and Pr. 84 "Rated motor frequency" according to the motor
specifications. (Setting "9999 (initial value)" in Pr. 80 or Pr. 81 selects
V/F control.)
Set "1" (offline auto tuning without rotating motor (for other than
MM-CF)) in Pr. 96, and perform tuning.
When the setting for the PM motor is selected in Pr. 998 "PM parameter
initialization", the PM sensorless vector control is selected.
[PM] on the operation panel (FR-DU08) is lit when the PM sensorless vector
control is set.

"8109": Parameter (frequency) settings for an IPM motor other than MM-CF
"9009": Parameter (rotations per minute) settings for an SPM motor
"9109": Parameter (frequency) settings for an SPM motor
