8.2.3. Execute Automatic Tuning (Adjustment Level 1)
l
Between the cases that the load weight is known and unknown, the procedure of automatic
tuning differs.
8.2.3.1 When the load weight is known.
l
Set the load weight by parameter LO. The unit of LO is [kg] and 0.1 kg step setting is possible.
l
For example, when the load weight is 5.5 [kg], the setting procedure will be as follows;
(1) Input the password.
(2) Set the load weight.
l
Input LO data that differs from the present setting. Otherwise automatic tuning will not be
carried out.
8.2.3.2 When the load weight is not known.

Caution : Make sure the work (or Motor) does not hit any obstacle when the Motor
makes a motion. Always stay in safe position.
à
The Motor needs to move at least ±20 mm when executing the
automatic tuning. If the application restricts the Motor movement, keep
room for ±20 mm Motor movement. The overtravel limits (OTP, OTM)
must be used to restrict the Motor moving range.
(1) Turn SVON (CN2) signal “ON” and inputting “SV” command makes the Motor in servo-on
states.

The Motor moves 10~20 mm back and forth to estimate the load inertia. When executing
estimation, a dot ( . ) keeps appearing in the display till the Motor stops.
