CHAPTER 5 SERVO ADJUSTMENT

5.2.3 Description of Operation

Two operation patterns of easy tuning are described.

 Slow running

Starting conditions

Conditions for starting slow running are indicated "" in the table below.

Slow running does not start if the conditions shown below are not satisfied ("NG1" is indicated).

If none of conditions are satisfied during operation, operation is stopped ("NG2" is indicated).

The gain reference value at the time of the start is kept as far as no resonance is observed.
