CHAPTER 5 SERVO ADJUSTMENT

Operation profile (in case of reciprocal motion)

The operation profile is shown below. "P□□" in the table indicates the number of the basic setting

parameter (PA1_□□).

*1) The result of automatic calculation can be checked with the PC Loader.

*2) 1 s or less reference values are assumed to be 1 s for easy tuning.

The frequency of a reciprocal motion is 25 cycles maximum, and that of a single-direction motion is 50

cycles maximum.

Details of tuning

Up to 50 easy tuning cycles are repeated while auto tuning gain 1 is automatically adjusted in the

range from 5 to 30.

Details of completion of action

The action completion method includes three profiles: normal completion, interruption by user, and

faulty termination. Each profile is described below.
