| | | | | | | | | | | | Signal name | * Setting function | Sequential mode Palletizing mode | External point designation mode | | | | Input/output | | | | Robot single operation | Input | The single operation mode is operative when this input is ON with the start input or start key set ON. In this mode, axis feed command and output command are inhibited. | Inoperative. | | | | Restart | Input | Even if the power is turned off or reset while this input is ON, contents of counter, etc., are not cleared. | Inoperative. | | | | Escape | Input | When this input is ON during execution of MVE command, an axis slows down and stops, and the system interprets that the relevant step has finished. | Inoperative. | | | | Pause (feed hold) | Input | ON: Feed hold (slowdown and stop). To restart, set ON the start input. To cancel, set ON the reset input. | | | | Program selection 2° Program selection 21 Program selection 22 | Input | Input signal for specifying a program number ( No.1 - No.8) at program selection. | Inoperative. | | | | Home return | Input | ON: Start of home return motion. (Initial setting is assigned to Pin 28.) | | | | Palletizing | Input | ON: Palletizing mode OFF: Sequential mode (While the easy, external point designation or pulse train input mode is selected, this input is invalid.) | Inoperative. | | | | Wait for input | Output | ON when the system is waiting for an input during program execution. | Inoperative. | | | | Pausing | Output | ON when an axis has slowed down and stopped after recognizing pause input. (OFF when the pause mode is canceled.) | | | | Ready | Output | ON when the teach pendant and RS232C are inoperative and no error is generated. | | | | | | | | | | | |
