Simulated welding<br />

Error handling<br />

Full simulation of a timer.<br />

Activated by setting sw_sim_weld TRUE. This will inhibit the start signal to the timer.<br />

The simulation time is defined in sw_sim_time. No preweld supervision is performed.<br />

Simulation in the timer<br />

Activated by setting sw_inhib_weld TRUE. This will set the current_enable signal low<br />

at the next weld. No preweld supervisions performed.<br />

Events in an error situation<br />

When SpotL is stopped by a supervision, the following take place:<br />

- The signal process_error is set.<br />

- An error message is displayed.<br />

- The error message is logged.<br />

Error situations<br />

The following error situations can occur:<br />

- Instruction parameter error.<br />

- Supervision error before welding.<br />

- Weld error.<br />

- Supervision error after welding and before the next motion.<br />

- Supervision error for gun pressure.<br />

- Supervision error for gun closure (SpotWare Plus)<br />

- Supervision error for gun opening.<br />

The supervision activities before and after welding can be modified by the user.<br />

In SpotWare Plus all the supervision behaviour described above, except weld error and<br />

parameter error, can be modified by the user.<br />

To stop execution with an error message, simply put the desired message in the<br />

assigned error string and it will show on the teach pendant.<br />

The behaviour below is programmed as default.<br />
