4.3 Test operation and gain adjustment of the PM sensorless 

vector control

4.3.1

Outline of the PM sensorless vector control

A PM (magnet) motor is a highly efficient motor compared to an induction motor. With this PM motor, highly efficient motor
control and highly accurate motor speed control can be performed.
Without using a speed detector such as an encoder, the motor speed is detected based on the output voltage and current of
the drive unit, and highly accurate control can be performed.

4.3.2

Automatic parameter setting in accordance with the motor (Pr.998) 

The above parameters can be set when 

Pr.160

 Extended function display selection = "0". (

Refer to page 161

.)

........Specifications differ according to the date assembled. 

Refer to page 294

 to check the SERIAL number.

POINT

The following conditions must be met to perform PM sensorless vector control.

· A PM motor must be used.
·

A specified combination of the S-PM geared motor capacity and the drive unit capacity must be used. 

· Single-motor operation (one motor run by one drive unit) must be performed.
· The overall wiring length with the motor must be 30m or less.

NOTE

Constant-speed operation cannot be performed in the low-speed range less than 300r/min. Generally, speed control
can be performed in the range that satisfies the ratio, 1:10. (Adjustable with 

Pr. 785

.)

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.

Performing PM parameter initialization automatically adjusts the parameter initial settings and setting ranges

required to drive the PM motor being used.

When using a PM motor other than the S-PM geared motor, perform offline auto tuning. 

Refer to page 105

 for

offline auto tuning.

Initialization is performed by setting 

Pr.998 PM parameter initialization

 or by choosing the mode on the operation

panel.
