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.
Set the motor. (Pr.9, Pr.71, Pr.80, Pr.81, Pr.83, Pr.84) (Refer to
Set "8093 (IPM motor)" 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) in Pr.96, and perform tuning.
Configure the initial setting for the PM sensorless vector control using Pr.998.
(Refer to page 145.)
When the setting for the PM motor is selected in Pr.998 PM parameter initialization,
the PM sensorless vector control is selected.
"8009": Parameter (rotations per minute) settings for an IPM motor
"8109": Parameter (frequency) settings for an IPM motor
"9009": Parameter (rotations per minute) settings for an SPM motor
"9109": Parameter (frequency) settings for an SPM motor
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
NOTE
• To change to the PM sensorless vector control, perform PM parameter initialization at first. If parameter initialization is
performed after setting other parameters, some of those parameters will be initialized too. (Refer to
parameters that are initialized.)
• The carrier frequency is limited during PM sensorless vector control. (Refer to
• Constant-speed operation cannot be performed in the low-speed range of 200 r/min or less.
• During PM sensorless vector control, the RUN signal is output about 100 ms after turning ON the start command (STF, STR).
The delay is due to the magnetic pole detection.
