Cycle parameters
Various cycle parameters in channel--specific GUD (Global User Data) must be
initialized for the machining cycles. The names and meanings of the GUD are listed
in the tables below.

SINUMERIK 802D sl/840D/840D sl/840Di/840Di sl/810D ISO Milling (PGM) -- 04.07 Edition
GUD7 for programmed cycle values (ISO dialect program data)
Description/use
Initial plane (current position on 1st call with G..),
retraction position active on G98
Reference plane, retraction position active on G99
(retraction is only possible to initial position with G87).
Final drilling depth
Retraction position, depending on G98/G99
(initial plane/R plane)
Feed rate for drilling
Dwell time at final depth (G82/G89/G76/G87)
1st drilling depth (single drilling depth), incremental
(G73/G83)
1st drilling depth, absolute (G73/G83)
Lift--off/in--feed distance (G76)
Speed for tapping (G74/G84)
Current G code of ISO Dialect0 drilling cycle
M function for spindle start (M3, M4) after spindle stop
GUD7 for cycle setting data (ISO dialect setting data)
Description/use
Safety clearance to reference plane
Retraction amount for chip--breaking (G73). The value "0"
means 1 mm or 1 inch. If it is need to specify 0 mm or 0
inch, set a smaller value than the movable resolution.
Angle offset for oriented spindle stop, tool must be
oriented in the reverse directionof retraction (G76)
The retraction direction is set by _ZSFI[5].
(improve to the specification which can set up "d" value for
G83
> 0 = value is used for anticipation distance (distance mi-
nimal 0.001)
= 0 = distance d is calculated internally
