CHAPTER 3 Operating Procedures
3 - 32
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.
(C) Tuning rotating speed
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 [Continuous pattern tuning start] button.
4- Confirm the safety, and then turn on the FOT terminal, ROT terminal, and SON
terminal in order named. A pattern operation is then continuously performed to
estimate the inertia.
