3.2.102.4 Weld1 mode: Time (C1446 = 0)
The value at the input WELD1−TIME is interpreted as a time value.
Output of status information
l WELD1−T−ERR = HIGH: The total length and the sum of times of the three sections
WELD1−LEN−C (close), WELD1−TIME (weld) and WELD1−LEN−O (open) do not agree. The
reasons may be as follows:
– Wrong profile selection
– Line speed too high
In such a case the welding time will be automatically reduced to avoid a disturbance of the motion
sequence.
l WELD1−DIR−ERR = HIGH: A negative master angle is assigned to the input WELD1−XIN.
Remedy:
– Invert master angle
– Invert direction of rotation of the welding bar drive at the function block CCTRL.
l WELD1−ON = HIGH: Welding phase is active
