Software 34049x-05
The cylindrical surface cycles 27, 28, 29 and 39 can now also be
used with modulo rotary axes. In the past, Machine Parameter 810.x
= 0 was required.
Cycle 403 does not check whether touch points and compensation
axis match. As a result, probing is also possible in a tilted coordinate
system (see "BASIC ROTATION Compensation via Rotary Axis
(Cycle 403, DIN/ISO: G403)" on page 331)
