The DI/DO signals listed below are used for loader control. These DI/DO
signals are stored in the loader control board. In an application system
that requires additional DI/DO signals, an I/O link interface is available
to enable external I/O expansion.
The loader control board of the Series 16i/18i/21i does not use these
DI/DO signals. All DI/DO signals are connected via an I/O link interface
to an external input/output unit.
Loader control (overtravel, hand open/close, air on/ off, etc.)
Workpiece feeder control (moving the workpiece feeder back and forth)
Loader operator’s panel control (teaching, emergency stop)
Brake control (brake application for emergency stop)
