Fronius TPS/i - Arc Break Monitoring

Arc Break Monitoring
Arc Break Monit-
oring
The arc break monitoring is a function that can be activated on the power source. The
function becomes active when arc breaks occur.
If the arc break monitoring is activated, the Robot motion release signal is set to Low.
The following can be set in order to use the arc break monitoring:
- The break length after which the arc break monitoring becomes active
- In which way the arc break monitoring is activated
• With "Ignore"
• With "Error"
Process if the arc break monitoring reacts to an arc break with "Error" – arc break monit-
oring set to 200 ms:
- If the arc breaks for 190 ms, the arc break monitoring is not activated
- If the arc breaks for 210 ms, the power source reports an error message and stops
the welding process
Process if the arc break monitoring reacts to an arc break with "Ignore" – arc break mon-
itoring set to 200 ms:
- If the arc breaks for 190 ms, the arc break monitoring is not activated
- If an arc breaks for 210 ms, the Arc stable signal is set to Low by the arc break mon-
itoring. Whether the Welding start signal remains High or is set to Low by the robot
depends on the setting selected on the robot.
