gundata Spot weld gun data<br />

Description<br />

Components<br />

Gundata is used to define spot weld gun specific data, to control the gun in an optimal<br />

way in the weld process.<br />

Gundata is used in spot weld instructions and has the following structure:<br />

- Number of electrode pairs.<br />

- Number of pressure levels.<br />

- Flag to indicate if a signal is required to test accurate gun closure.<br />

- Flag to indicate if a signal is required to test accurate gun opening.<br />

- Counter for the number of welds done and maximum allowed number (one<br />

counter and maximum value for each pair).<br />

- Closing times.<br />

- Opening times.<br />

nof_tips (number of tips) Data type: num<br />

Number of electrode pairs (1 or 2)<br />

nof_plevels (number of pressure levels) Data type: num<br />

Number of pressure levels (1 - 4)<br />

close_request (closure request) Data type: bool<br />

If the flag is TRUE, the ordered pressure level is tested before the weld may start.<br />

open_request (opening request) Data type: bool<br />

If the flag is TRUE, the gun open signal is tested before the next motion is<br />

released. The time out is defined by sw_go_timeout.<br />

(See Predefined Data and Programs - System Module SWUSER)<br />

Note. The open_time must elapse before the test is done (see below).<br />

If the flag is FALSE, the next motion is always released after open_time (see<br />

below).<br />
