Cabinet features Improved Resistance to Heat and Dustproofingand Improved Reliability in Global Environments.

The AX21 controller can be used with a wide variety of applications, including arc welding, spot welding and material handling, addressing all kinds of needs in production processes.

Controller with Higher Reliability and Maintainability

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.

• Size and weight of drive unit reduced and single-touch connection of control cable improves maintainability
• Up to 16 axes controllable simply by adding an extension case

Two-point Tool Length Setting Function

Simple one-button tool correction

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

Robot Diagnostic Tool (Option)

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.

Right: Motor speed and actual current of each axis displayed on the teach pendant.

Automatic Calibration Function (Option)

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.

Arc Data Monitor Function

Monitor welding current, welding voltage, wire feed load, etc. on the teach pendant. Connecting a DL350 additionally shows spatter suppression rates.

Increased Sampling Frequency Provides Higher Detection Accuracy

The process is used to detect instantaneous arc outages, arc outages in short tack welding, etc.

Welding Characteristic Data Automatic Adjustment Function

Adjustments are made so that the actual welding current/voltage will be output in the conditions as taught by accounting for differences in the welding environment such as changes in wire extension.

Reduction of Pauses During Welding

With the previous model, arc outage during welding caused the robot to pause.

AX21 allows automatic restoration of robot operation under predefined conditions, such as the restart position and number of restarts.

• Productivity of the robot is significantly improved.
• Helps reduce system construction costs.

Software PLC Function

Interface PLC with line control panel, which is provided by user, can be significantly simplified – reducing your system cost.

Simplified Wiring by Field Network Capability

For I/O interface with line control panel, field networks such as DeviceNet and CC-Link can be used on top of relay contacts, allowing wiring cost reduction by simplified wiring and flexible system construction according to the user's needs.
