5.5 Inaccurate results
Description
Search results are inaccurate.
Possible causes
1 Search result data is being used improperly. Verify that the RAPID search
instructions are being used correctly. See User's guide on page 33.
2 The sensing voltage is too low. Activate the SmarTac board by turning
doSE_SENSOR on, and doWIRE_SEL and doSE_REF off. Check that there is
at least 25 VDC measured between the torch sensing surface and the part.
Ideally there should be about 38 VDC present. A reading lower than 25 VDC
indicates that there is a significant loss that will make search results
inaccurate. Low voltage can result from contaminated coolant, defective
torches, and grounded welding wire. See False-positive torch contact on
page 77 for more details.
3 The TCP is moving. Check to see that the torch is securely mounted to the
robot and that no movement is detected when searching.
