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
Set "3003 or 3103" in Pr.998 PM parameter initialization or select "3003" in
Setting value "3003": parameter settings for MM-CF IPM motor (rotations per minute)
Setting value "3103": parameter settings for MM-CF IPM motor (frequencies)
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
Select the start command and speed command.
Test run
page 172.)
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
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.)
Perform offline auto tuning for a PM motor. (Pr.96) (Refer to
Set "1" (offline auto tuning without rotating motor (for other than MM-CF)) in Pr.96,
and perform tuning.
Configure the initial setting for the PM sensorless vector control using Pr.998.
(Refer to page 173.)
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.
