Frame variables/assigning values to frames

Values can be assigned directly, frames can be

chained or frames can be assigned to other frames

in the NC program.

Direct value assignment

$P_PFRAME=CTRANS (X, axis value, Y, axis value, Z, axis value, ...)

$P_PFRAME=CROT (X, angle, Y, angle, Z, angle, ...)

$P_PFRAME=CSCALE (X, scale, Y, scale, Z, scale, ...)

$P_PFRAME=CMIRROR (X, Y, Z)

Programming $P_BFRAME is carried out analogous

to $P_PFRAME.

Explanation of the commands

You can use these functions to assign frames or

frame variables directly in the NC program.

You can program several arithmetic rules in

$P_PFRAME=CTRANS(...):CROT(...):CSCALE...

Please note that the commands must be connected

by the colon chain operator (...):(...).

This causes the commands firstly to be linked and

secondly to be executed additively in the

programmed sequence.
