2.5.3 Special reactions
Overstore
Overstoring in RESET state of:
• Frames (zero offsets)
• Active plane
• Activated transformation
• Tool offset
immediately affects the actualvalue display of all axes in the channel.
MMC inputs
If operations on the operator panel are used to change the values for
"Active frame" (zero offsets, "Parameters" operating area)
and
"Active tool length compensation" ("Parameters" operating area),
one of the following actions is used to activate these changes in the display:
• Press the RESET key
• Reselect:
• Reset:
• Part-program start
MD9440
If the MMC machine data
MD9440 ACTIVATE_SEL_USER_DATA
for the operator panel is set, the entered values become active immediately in RESET state.
When values are entered in the part-program execution stop state, they become effective
when program execution continues.
Actual-value reading
If the actual value of $AA_IW is read in the WCS after activation of a frame (zero offset) or a
tool offset, the activated changes are already contained in the result read even if the axes
have not yet been traversed with the activated changes.
