Logical
Number
Input Name / Function
20010 EXTERNAL START
Functions the same as the [START] button in the programming pendant. Only the
rising edge of the signal is valid. It starts robot operation (playback). This signal is
invalid if external start is prohibited from the playback condition display.
20012 CALL MASTER JOB
Only the rising edge of the signal is valid. It calls up the top of the robot program, that
is the top of the master job
1)
. This signal is invalid during playback, during teach-lock
and when play master or call is prohibited (set from the playback operation condition
display).
20013 ALARM/ERROR RESET
After an alarm or error has occurred and the cause been corrected, this signal resets
the alarm or error.
20015 SELECT PLAY MODE
The play mode is selected when the mode key on the programming pendant is set at
“REMOTE”. Only the rising edge of the signal is valid. When this selection signal
assigned concurrently with other mode selection signal, the teach mode is selected on
a priority basis. The signal is invalid while EXTERNAL MODE SWITCH is prohibited.
20016 SELECT TEACH MODE
The teach mode is selected when the mode key of the programming pendant is set at
“REMOTE”. The other mode selection is unavailable when this signal is ON; the
signal is selected by priority even when the other selection signal is ON, enabling the
teach mode selection.
20020 INTERFERENCE 1 ENTRANCE PROHIBITED
If the manipulator attempts to enter the cube 1
2)
area while this signal is ON, the
manipulator goes to wait status (with servo power ON). During wait status, the
manipulator operation restarts if this signal turns OFF.
20021 INTERFERENCE 2 ENTRANCE PROHIBITED
If the manipulator attempts to enter the cube 2
2)
area while this signal is ON, the
manipulator goes to wait status (with servo power ON). During wait status, the
manipulator operation restarts if this signal turns OFF.
20022 WELDING ON/OFF (From sequencer)
This signal inputs the welding ON/OFF selector switch status from the sequencer in
the interlock unit. The WELD ON/OFF signal is output to the Power Source according
to this signal and the manipulator status.
20023 WELDING PAUSE (From sequencer)
This signal is used to move the manipulator to the home position when an error
occurs in the Power Source or the gun.
The robot ignores the spot welding instruction and operates playback motion.
20024 INTERFERENCE 3 ENTRANCE PROHIBITED
If the manipulator attempts to enter the cube 3
2)
area while this signal is ON, the
manipulator goes to wait status (with servo power ON). During wait status, the
manipulator operation restarts if this signal turns OFF.
20025 INTERFERENCE 4 ENTRANCE PROHIBITED
If the manipulator attempts to enter the cube 4
2)
area while this signal is ON, the
manipulator goes to wait status (with servo power ON). During wait status, the
manipulator operation restarts if this signal turns OFF.
20050
3)
TIMER COOLING WATER ERROR
This signal monitors the status of timer cooling water. The manipulator displays alarm
and stops when this signal is input. The servo power remains ON.
20051
3)
GUN COOLING WATER ERROR
This signal monitors the status of gun cooling water. The manipulator displays alarm
and stops when this signal is input. The servo power supply remains ON.
