(2) Procedure for performing an off-line tuning process while verifying individual

steps

1- In the opening window, click the [Test Run and Adjustment (T)] button. The

following window then opens (click the Offline tuning tab).

2- Enter the following parameters which are required for tuning:

(A) Speed control cut-off frequency

Set the speed control cut-off frequency for off-line tuning. Enter a setting at

which no hunting occurs.

(B) Tuning inertia initial value

Set the inertia for the beginning of off-line tuning. When an approximate inertia

value is known, make this entry to ensure that tuning is rapidly completed. If

the approximate inertia value is not known, you do not have to make this entry.

If you do not make this entry, the off-line tuning function estimates the inertia.

Enter the rotating speed for off-line tuning. If you are sure that the initial value

does not damage the machine connected to the servomotor, you can use the

initial setting.

(D) Acceleration/deceleration time

Set the pattern operation acceleration/deceleration time for off-line tuning. If

you are sure that the initial value does not damage the machine connected to

the servomotor, you can use the initial setting.

3- Click the [1 pattern tuning start] button.

4- Confirm the safety, and then turn on the FOT terminal, ROT terminal, and SON

terminal in order named. A one-pattern operation is then performed to estimate the

inertia.
