Logical Input Name / Function
Number
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
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
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
manipulator goes to wait status (with servo power ON). During wait status, the
manipulator operation restarts if this signal turns OFF.
20022 WORK PROHIBITED (Arc Generation Prohibited)
Arc generation is prohibited while this signal is ON. Arc generation starts when this signal
turns OFF inside the arc-generation area. Use this signal to confirm teaching.
20023 WORK RESPONSE (Pseudo Arc ON Response)
This signal is used as a pseudo signal in cases that "Arc Generation Confirmation" signal
is not equipped on a welding power supply. Wire this signal ON normally (short to OV).
20026 WEAVING PROHIBITED
Weaving is prohibited while this signal is ON. Use this signal to check taught steps and
movements without performing the weaving operation.
20027 SENSlNG PROHIBITED
Arc sensing is prohibited while this signal is ON. Use this signal to check taught steps and
movements if an arc sensor is mounted.
1 A master job is a job (program) which can be called by CALL MASTER JOB.Other functions are the same as for
normal jobs. Normally, the parent job, which manages the child jobs called up immediately after the power is
turned ON, is set as the master job.
