Content
This signal specifies that welding has been completed.
When the welding command manual spot operation is
executed, it is used as a confirmation signal. When
there is no LS open/close confirmation, the welding
sequence ends and the next step is executed.
This signal specifies an error in welding results or in
the welder. During welding, an alarm occurs and the
robot stops.
Specifies when a wire stick is detected. An alarm
occurs and the robot stops.
Specifies a timer cool water error. An alarm occurs
and the robot stops. The servo power stays on.
Specifies a gun cool water error. An alarm occurs and
the robot stops. The servo power stays on.
Specifies an error from the gun transformer is
transmitted directly to the robot controller. It is
normally ON (NC), and when OFF, an alarm occurs.
The servo power stays on.
Interlock circuit board, etc. PLC welder ON/OFF select
switch. Welder status signal which outputs welder
ON/OFF signal. While in the ON status, if the welder
is switched OFF, spot welding is not performed.
If this signal occurs after tip replacement, turn off the
tip replacement demand signal, and the tip hit count is
cleared.
When there is a 2 step stroke gun, this signal specifies
stroke full open status.
The open/close confirmation LS of a single gun and
short open confirmation LS of the 2 step stroke gun
are connected, and the gun open/close confirmation is
performed.
Specifies the gun pressure status.
An alarm occurs if the air pressure is low. The servo
power stays on.
