2.8 General I/O Signal Assignment
2-70
*1
The operation origin cube and Cube 24 are same.
*2
This signal is not output during operation.
*3
This signal can be allocated to any general output signal at the I/O allocation display in
operation condition.
*4
This signal can be select “USE” or “NOT USE” by pseudo input signal ”822x”. If “NOT
USE” is selected, this signal can be used as general input signal.
3020
IN CUBE 1
This signal turns ON when the current
tool center point lies inside a pre-defined
space (Cube 1). Use this signal to pre-
vent interference with other manipulators
and jigs.
*3
WELDING COMMAND
This signal outputs execution command
signal to the welder. This signal is not
necessary for a welder which is exe-
cuted using the WELDING CONDITION
signal.
3021
IN CUBE 2
This signal turns ON when the current
tool center point lies inside a pre-defined
space (Cube 2). Use this signal to pre-
vent 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 center point lies inside a the opera-
tion origin area. Use this signal to evalu-
ate 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.
