Programming Of Absolute Zero Point (G92) - YASKAWA MOTIONPACK-110 Descriptive Information

4.2.18 PROGRAMMING OF ABSOLUTE ZERO POINT (G92)
Before programming movement commands, an absolute coordinate system may be
established, so that all the subsequent absolute movement commands will be effected on
this coordinate system.
(1)lG92 X..-Y... z...; I
With this command, the current machine position is entered as a point (X, Y, Z) in one
arbitrarily selected absolute coordinate system. That is, this command designates the
signed distances in the three coordinate directions from a desired coordinate zero
point (0, 0, 0), designating zero point in this way. See Fig. 4.30.
(2) G92 cannot be programmed with other G codes, F, M, or T codes in the same block.
NOTE
1. In principle, program G92 while all position offset commands are
cancelled.
2. When the power is turned on, the current position is set as coordinate
(0, 0, 0). Be sure to execute the return motion to the reference point
before starting operation.
(3) As a special example, coordinate shift equivalent to G92 can be made by position cancel
operation from the CRT control station.
