Digital Inputs Welding start The rising edge of the Welding start signal starts the welding process. (Welding on) - The welding process runs for as long as the Welding start signal is active. Single Bit Exceptions: The Robot ready signal is deactivated or the power source is re- porting an error (for example: overtemperature, too little coolant, etc.).

Description of special 2-step mode characteristics: To select welding parameters using the analog set values and the character- istic number (characteristic ID), the correct characteristic number must be used. The characteristic numbers can be found on the website of the power source, in the characteristics overview.
The Gas on signal can only be set if the Robot ready signal is set at the same time. If this is not the case, the gas flow must be activated by pressing a but- ton on one of the Fronius system components (power source, wirefeeder, torch hosepack, etc.).
The Wire backward signal can only be set if the Robot ready signal is set at the same time. If this is not the case, retraction of the wire electrode must be controlled using the wire-return button on one of the Fronius system components (wirefeeder, torch hosepack, etc.).

Other effects of the WireSense start signal: As soon as the signal is active, the forward and backward movement of the wire electrode begins.

Limit Monitoring - functions and activation Functions of Limit Monitoring monitors the welding parameters of the welding process. Limit Monitoring Limit Monitoring indicates whether the weld is performed within the pre- defined limit values of the weld specification (= job set values). If Limit Monitoring determines that the actual values are outside the defined limits, the weld seam should be checked.
Prerequisites for Job mode must be enabled for each power source. the successful At least 1 job must be assigned to each weld seam use of Limit It is recommended to use several jobs per weld seam if significant influ- Monitoring encing factors change during welding, such as robot speed, angle of at- tack of the welding torch, Stick-Out, etc.

Current monitor- Serves to: Set the current set value and the desired limits. Monitor the current actual value per weld seam / job. Current monitoring Adjustable parameters: Current set value: 0 to 100 A Lower current limit: -10 to 0 A Upper current limit: 0 to 10 A Time limit for the reaction of Limit Monitoring:...
Wirefeeder monitoring Adjustable parameters: Wirefeeder set value: 0 to 100 m/min Lower wirefeeder limit: -10 to 0 m/min Upper wirefeeder limit: 0 to 10 m/min Time limit for the reaction of Limit Monitoring: Off / 0 to 10 seconds Explanation for setting from 0 to 10 seconds: If, for example, 5 seconds are set, Limit Monitoring will only react after a limit has been exceeded or undershot continuously for 5 seconds.
Page 74
Example: A weld seam consists of 4 jobs, each with a duration of 4 seconds. Limit Monitoring ignores the first 3 jobs and only records the last job. For this reason, a welding time set value of at least 16 seconds must be set for the last job (4 x 4 seconds) in order to prevent Limit Monitoring from un- intentionally issuing a notification.
Energy monitor- Serves to: Set the energy set value and the desired limits. Monitor the energy input per weld seam / job. If a weld seam consists of 2 or more jobs, the energy input of the previously wel- ded job must be added for the subsequent jobs in the weld sequence. Example: A weld seam consists of 4 jobs, with an energy input of 40 kJ each.
