12.29.2 General hardware conditions for ”Extended measurement”
No check is made to ascertain whether R parameters which are also required by other
functions are being overwritten. Which R parameters within the available parameter range are
used is left to the discretion of the user.
If the programmed G720/G721 variant (probe selection, edge selection, etc.) is not supported
by the measuring circuit hardware, the axis-specific RESET alarm 1076* "Hardware
measurement" is output.
The following steps can be taken to avoid this problem:
•
When taking measurements with the second probe (MT = 2), program PCA and/or 611D
axes only.
•
In mixed operation 611D/PCA with SPC/HMS, program "first probe input" (MT = 1) and
"negative edge" (MF = 1) only.
Alarm 1076* is also output if the active measuring system is switched over when
measurements are in progress.
