General
The Independent Axis option is used to make an external axis (linear or rotating) run independently of the other axes in the robot system. The option also includes the function ‘Axis Reset’, which can reset the Axis position counter from RAPID. Axis Reset is useful for repeated maneuvers, where mechani cal reset of the axis (mechanically turning back the axis) would mean loss of cycle time in the process.
Features
• Movement of an axis, independent of the robot motion
• Independent movements, programmed with absolute or relative positions
• Continuous rotational/linear movement of an axis
• Speed regulation of the independent axis
• Reset of Axis position counter (axes 4, 6 and additional (rotating) axes)
Application
Performance
The movements will be made with the same performance as additional axes without Independent Axis.
Requirements
There are no software or hardware requirements for this option.
Limitations
If an axis has a gear ratio which is not an integer number, fine calibration is required after resetting the revolution counter on the serial measurement board, if a precise axis position is needed in the application. Internal and customer cabling and equipment may limit the ability to use independent axis functionality on axis 4 and 6. For information about what capability a specific robot’s axis 4/6 has, please contact ABB
