Positional Data
3.6 Zero offset frame, (G54 to G57, G505 to G599, G53, G500/SUPA)
Parameters
G54 to G57
G505 ...G599
G53
G500
SUPA
G153
For more information please refer to Frame section.
Offset of the zero in the Cartesian coordinate system by frames such as
• Programmable zero offset, e.g., TRANS, ATRANS
• Programmable rotations, e.g., ROT, AROT
• Programmable scalings, e.g., SCALE, ASCALE
• Programmable mirrorings, e.g., MIRROR, AMIRROR
Example
In this example, three workpieces, arranged on a pallet according to the zero offset values
G54 to G56, are machined successively. The machining sequence is programmed in
subprogram L47.
100
Call the second to fifth settable zero offset/frame
Call the 6th to the 99th settable zero offset
Non-modal deactivation of current settable zero offset and
programmable zero offset
G500=zero frame, default setting,
(contains no offset, rotation, mirroring or scaling)
Deactivation of settable zero offsets/frames (G54 to G599) until the
next call.
Activation of the total basic frame ($P_ACTBFRAME).
G500 is not 0
Activation of first settable zero offset/frames ($P_UIFR[0]) and
Activation of total basic frame ($P_ACTBFRAME), or a modified basic
frame is activated.
Non-modal deactivation, including programmed offsets, handwheel
offsets (DRF), external zero offset and PRESET offset.
Non-modal suppression of settable, programmable and total basic
frame
