Output Name / Function
3010 RUNNING
This signal signifies that the job is running.
(Signifies that the job is running, system status
is waiting reserved start, or test run is running.)
This signal status is the same status as
[START] in the playback panel. 3023 INTERMEDIATE START OK
This signal turns ON when the manipulator
operates. It turns OFF when the currently exe-
cuted line is moved with the cursor or when
editing operation is carried out after HOLD is
applied during operation. Therefore, this signal
can be used as a restart interlock after a HOLD
is applied. However, it also turns ON in the
TEACH mode and TEACH MODE SELECTED
signal must be referred together.
3011 SERVO IS ON
This signal signifies that the servo power is
turned ON, internal processing such as current
position creation is complete, and the system is
able to receive the START command. This sig-
nal turns OFF when the servo power supply
turns OFF. It can be used for XRC status diag-
nosis for an external start. 3024 IN CUBE 3
This signal turns ON when the current tool cen-
ter point lies inside a pre-defined space (Cube
3). Use this signal to prevent interference with
other manipulators and jigs.
3012 TOP OF MASTER JOB
This signal signifies that the execution positio
is the top of the master job. This signal can be
used to confirm that the master job has been
called.
*2
3025 IN CUBE 4
This signal turns ON when the current tool cen-
ter point lies inside a pre-defined space (Cube
4). Use this signal to prevent interference with
other manipulators and jigs.
3013 ALARM/ERROR OCCURRED
This signal signifies that an alarm or an error
occurred. If a major error occurs, this signal
remains ON until the main power is turned
OFF. 3040
*4
WELD ON/OFF
Outputs a signal input from the interlock panel,
etc.considering the robot status.
3014 BATTERY ALAR
This signal turns ON to notify that the battery
requires replacing when the voltage drops from
the battery for backup memory of the encoder.
Major problems may result if memory data is
lost because of an expired battery. It is recom-
mended to avoid these problems by using this
signal as a warning signal. 3041
*3
WELD ERROR RESET
This signal commands the reset error status of
the welder. This is operated with the program-
ing pendant operation.
3015 to
3017 REMOTE/PLAY/TEACH MODE SELECTED
This signal notifies the current mode setting.
These signals are synchronized with the lamps
[REMOTE] and [MODE] in the playback panel.
The signal corresponding to the selected mode
turns ON. 3042 to
3045
*3
WELD CONDITION (Level signals)
1(1), 2(2), 4(3), 8(4), 16(5), 32(6), 64(7), 128(8)
Sets the welding conditions for the welder.
The output format can be selected as binary or
discrete (bit number). It can handle up to 255
conditions. Most-significant bit is the parity bit
(when specified).
3020 IN CUBE 1
This signal turns ON when the current tool cen-
ter point lies inside a pre-defined space (Cub
1). Use this signal to prevent interference with
other manipulators and jigs.
*3
WELDING COMMAND
This signal outputs execution command signal
to the welder. This signal is not necessary for
welder which is executed using the WELDING
CONDITION signal.
3021 IN CUBE 2
This signal turns ON when the current tool cen-
ter point lies inside a pre-defined space (Cub
2). Use this signal to prevent interference with
other manipulators and jigs.
*3
STROKE CHANGE1
SINGLE SOLENOID
DOUBLE SOLENOID
This is a signal, when a double stroke gun is
used, to change the open stroke of the welding
gun.
3022
OPERATION ORIGIN POINT (IN CUBE 24)
*1
This signal turns ON when the current tool cen-
ter point lies inside a the operation origin area.
Use this signal to evaluate whether the robot is
in the start position.
3046
*3
GUN PRESSURE INSTRUCTION
This outputs a gun pressure instruction.
3047
*3
TIP REPLACEMENT REQUEST
This is output when the number of strokes
reaches the set value for tip replacement.
