5.7 Interpolation Control Mode

Use the "interpolation control mode" to adjust command responses of a system with two or more

servomotor axes such as the X-Y table when performing synchronous operation or interpolation

Check the following conditions to perform adjustment.

 Keep consistency in the mechanical configuration and specifications of each axis to the largest

extent (ball screw pitch, diameter, length, etc.).

 The backlash of the mechanical system is not large and the belt is free from deflection.

 Commands sent from the host are common among axes.

Parameters used for gain adjustment are shown in the table below.

Tuning mode selection

Load inertia ratio

Auto tuning gain 1

Moving average S-curve time

time constant

The other parameters are automatically adjusted.

However, auto tuning gain 2 becomes disabled.
