20.1 Zero offsets and presets
20.2 Work zones
The icon may be used to select the following options:
• Machine zero. It cancels any zero offset and assumes
the machine zero (home) as reference.
• Absolute zero offset. It permits defining, enabling or
de enabling the absolute zero offsets (G54 to
G57).
The zero offset is selected with an icon.
• Incremental offset: It permits defining, enabling or
de enabling the incremental zero offsets (G58 or
G59). The zero offset to be activated is selected with an
icon.
• Preset: The preset value for the active axes may be
edited on the screen. If any of them is not to be preset,
leave its field empty.
The cycle internally generates a block with function G53,
G54...G59 or G92.
Pressing the [ZERO] key accesses the zero offset table.
The icons may be used to defined the following options:
• Select the work zone to act upon. Up to five different
zones may be defined.
• Type of action to carry out with the zone. A zone may be
defined, enabled, enabled or disabled.
• Define the type of zone. Each one of them may be
defined either as a no-entry or no-exit zone.
The numeric fields permit editing the lower and upper limits
of the zone. The limits are defined on the X, Y, Z axes. To
only define either the upper or the lower limit, leave the
values of the other limit blank.
The cycle internally generates up to three blocks with
functions G20, G21 and G22.
