The loader operator’s panel is used to jog the loader and to perform
teaching. For the loader operator’s panel, the I/O signals described below
are stored on the loader I/O board.
DI = 8 points (24–V input)
DO = 6 points (24–V sink output)
DO = 4 points (24–V source output)
DI = 1 point (24–V input for emergency stop)
These I/O signals are used for switch input of the loader operator’s panel
and for driving the LED display.
