: Slip frequency

: Motor primary constant

: Motor secondary constant

: Motor excitation constant

: Magnification of load inertial moment

: Rated capacity ratio of motor to inverter

6	To use vector control, automatic torque boost and automatic energy-saving, motor constant setting (motor tuning)
	is required. The following three methods are available to set motor constants (for automatic torque boosting,
	however, two methods are available):
	1)	Using the automatic torque boost (			) for setting the V/F control mode selection
		(	) and auto-tuning (	) at the same time
	2)	Setting the V/F control mode selection (				) and auto-tuning (	) independently
	3)	Combining the V/F control mode selection (				) and manual tuning

Sensorless vector control may not operate properly if the motor capacity differs from the applicable rated capacity of the inverter by more than two grades.

[Selection 1: Setting by automatic torque boost]

This is the easiest of the available methods. It conducts vector control and auto-tuning at the same time.

Set the automatic torque boost parameter ( ) to " " (Sensorless vector control + auto-tuning).

See Section 5.2 for details of the setting method.

[Selection 2: Setting sensorless vector control and auto-tuning independently]

This method sets sensorless vector control or automatic torque boost, and auto-tuning independently.

Specify the control mode in the V/F control mode selection parameter "( )" and then set auto-tuning.

Set the auto-tuning parameter ( ) to " ".
