6.5.3 One-parameter Tuning Example

The following procedure is used for one-parameter tuning on the condition that the tuning mode is set to 2, or
3. This mode is used to reduce positioning time.

6.5 One-parameter Tuning (Fn203)
Operation
Measure the positioning time after setting the mass ratio
(Pn103) correctly. Tuning will be completed if the specifica-
tions are met here. The tuning results will be saved in the SER-
VOPACK.
The positioning time will become shorter if the FF level is
increased. The tuning will be completed if the specifications
are met. The tuning results will be saved in the SERVOPACK.
If overshooting occurs before the specifications are met, go to
step 3.
Overshooting will be reduced if the FB level is increased. If the
overshooting is solved, go to step 4.
The graph shows overshooting generated with the FF level
increased in step 3. In this state, the overshooting occurs, but
the positioning setting time is short. The tuning will be com-
pleted if the specifications are met. The adjustment results are
saved in the SERVOPACK. If overshooting occurs before the
specifications are met, repeat steps 3 and 4.
If vibration occurs before the overshooting is eliminated, the
vibration will be suppressed by the automatic notch filter.
Note:
The vibration frequencies may not be detected if the amplitude
is too small. If that occurs, press the
the vibration frequencies.
The adjustment results are saved in the SERVOPACK.
