PC-based management for compatibility
with various applications.
The AX21 controller can be used with a
wide variety of applications, including are
welding, spot welding and material handling, addressing all kinds of needs in production processes.

Improved cooling efficiency and dustproofing provides reliable use in
severe environments, including production lines with high duty cycles and high-temperature and high-humidity areas.

*Easier addition of external axes than previous model.

Two-point Tool Length Setting Function

This process eliminates the need for adjustment with torch gauge, significantly reducing robot down time.

*Simple and quick maintenance functions

Robot Diagnostic Tool

AX21 features improved maintainability by modularization of parts and simplified cable wiring.
Users can check preventive maintenance and abnormality diagnosis with the optional Robot Diagnostic Tool.

Automatic Calibration Function
*Torch Deviation is Automatically Detected and Calibrated
A deviation detection program can be run at regular intervals to see if there is any error. If deviation is detected, the calibration program is automatically run for correction.

This prevents weld failure due to deviation, thereby helping reduce weld failure rates.
