3.8.3.8 Axis Clamp/Unclamp
The axes can be clamped by miscellaneous function M10 and unclamped by miscellaneous function M11. The list of
axes with clamps is defined by machine parameter P8 (see Parameter Manual).
If function M10 is present (axis clamp if there is no movement), the system detects the change of state of variables
AXMVTaxis (where axis = 0 to 31) on the axes with clamps.

REMARK If the axis is still moving at block n + 1, variable AXMVTt (where t = 0 to 31) remains
high and the blocks are sequenced.
3.8.3.9 Tool Number: %Rg7C.L
Variable Mnemonic
(group 1 to 8)
Description
%Rg7C.L OUTIL1 Tool Number Requested by Group g
OUTIL8 Contains the tool numbers (decimal values from 0 to 65535).
T functions are considered as pre-move and modal by the system, which does not
wait for a response.
