Product Introduction

The FT21 SERVOPACKs uses mode (gain) switching, predictive control, and quadrant projec-
tion correction to improve trajectory tracking performance. They are designed for use in con-
touring and other metal processing. Clearance control that uses a gap sensor has also been
implemented to enable applications with laser processing machines.
This section describes the main features.
• You can use mode (gain) switching, predictive controls, and quadrant projection correction to
suppress radial reduction when cutting circles and projections when switching quadrants.
These enable high-speed, high-precision processing.
• You can use clearance control with a gap sensor to perform high-precision control of the gap
between the workpiece and control target.
