Tool cycles with the following functions are available for tool measurement:
• L972 – Calibrate tool probe
– Measure tool of L1 or L2 with tool types 1 ... 10, 26, 28,
31 ... 38 with one tool offset number
– Automatic tool measurement of L1 and/or L2 with tool types
1 ... 10, 26, 28, 31 ... 38 with one tool offset number
• L982 – All functions of L972
– Automatic tool measurement of L1 and/or L2 and R
with tool types 28, 37, 38
with one or two tool offset numbers.
Selection: Length and/or radius compensation
Cycle L982 needs approx. 45 % more memory space than L972 and its running time is
approx. 20 % slower.
The 3rd and 4th decimal place of R23 are additionally used for coding the measurement
variant of L982.
R23=4321
