Features
This monitors the welding status during analog welding. Values available for monitoring are the current target voltage/current/speed/weaving offset/digital output signal and measured voltage/current and welding status. If measured voltage/current is not set (if ch_v_in and ch_c_in are not set during app_weld_enable()), the output of the corresponding values are set equal to the target voltage (v_target)/feeding speed (f_target). In addition, it is possible to check the fail status using the welding status factor.

Value |
Description |
|---|---|
|
v_target |
Current Target Voltage (V) (target with adjustment applied) |
|
f_target |
Current Target Feeding Speed (m/min) or Target Current (A) (target with adjustment applied) |
|
vel_target |
Current Target Speed (mm/sec) (target with adjustment applied) * Take note that the unit is different from that of the monitoring output unit (cm/min) of the teaching pendant |
|

|
status |
Non-weld:0, Weld (Normal): 1, Weld (Abnormal): 9, Dry-run: 99 |
