Control State
Any except while welding
Description Reports the current settings of the Control system displacement limit checking parameters.
NOTES:
The units of the limit fields parameters depend on the value of the UNITS parameter as
follows:
IN/1000: 1 = 0.001 inches; 10 = 0.01 inches
MM: 1 = 0.01 mm; 10 = 0.1 mm
Initial and final thickness are positive if the electrodes move farther apart and negative if they
move closer together (in relation to the “zero setting”). The reference “zero setting” for
thickness measurements may be set using the
DISPZERO command (see Host Originated
Commands section).
Displacement is positive if the electrodes moved closer together during the weld and negative
if they moved further apart.
Command DISPZERO ad_counts<crlf><lf>
Control State Any except while welding
Description Reports the current “zero setting” of the Control system displacement measuring device.
This value is in a/d converter counts (not actual position). If zero, the position of the upper
electrode at the start of the next weld will establish the new zero setting.
NOTE : This zero setting is the reference position for the initial and final thickness
measurements.
