Setting procedure of PM sensorless vector
control (speed control)
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
for the
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.
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 operation command. (Refer to
Select the start command and speed command.
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.
Perform offline auto tuning for a PM motor.
(Pr.96)
(Refer to
.)
Configure the initial setting for the PM sensorless vector control using
Pr.998
.
(Refer to
When the setting for the PM motor is selected in
Pr.998 PM parameter initialization
,
the PM sensorless vector control is selected.

"8109": Parameter (frequency) settings for an IPM motor
"9009": Parameter (rotations per minute) settings for an SPM motor

Set "1" (offline auto tuning without rotating motor) in
Pr.96
