Cancellation
When enabled by (G24+ ...), conversion is cancelled by:
- G24- with no argument,
- turning the machine off and back on.
Properties of the Function
The conversion arguments are modal. After cancellation by G24-, it is possible to
reprogramme G24+ followed all the arguments or G24+ alone in the block.
The conversion defined by function G24+ is applied immediately and remains valid
after a reset.
Notes
The X, Y and Z origins define the origin of the matrix reference system with respect
to the basic reference system declared by DAT1 + DAT2 (and possibly DAT3). These
origins must mandatorily:
- follow function G24+,
- precede coefficients P, Q and R.
It is possible to enable the conversion matrix before homing on the axes (for instance
to retract the tool according to the head position after applying power).
The conversion matrix must not be enabled when homing is requested on an axis.
Otherwise, the system generates error message 24 in homing mode.
Function G24 can be used for other applications than rotation of the programming
plane in space (for instance for correction of axes that are not orthogonal). In this
case, the values of the conversion matrix coefficients must be between -8 and +8 (if
not, the system generates error message 24). The same is true for the values of the
inverse matrix calculated by the system. It should be noted that it is not necessary
to comply with the angle crossing speeds and maximum accelerations.
Error Numbers and Messages
Error 2: No + or - sign after function G24.
Error 14: Inclined plane option not enabled.
Error 24: Error in declaration of an inclined plane:
- Activation of the function when it is already enabled.
- Incomplete declaration of the arguments of the function.
- The axis of the pivot point does not exist or is not servo-controlled.
- Incoherent value of one of the matrix terms.
- Programming of an inclined plane axis prohibited under G52.
