The address letter for the input of the angle of rotation
Settable coordinate rotation
The values can be entered in various ways:
• Via softkeys and keyboard in the input display "Angle of rotation"
• There is no distinction between coarse and fine setting
• Input of the value for angle of rotation "A" via keyboard in input display KD
• Programming of program parameters (@ commands) in the part program
• The angle of rotation "A" can be input via the universal interface for G54 ... G57 or for
G154 ...G157
The rotation is activated by G54 ... G57 in the part program. If a zero offset and a coordinate
rotation are set under the settable coordinate rotation, first the zero offset is performed and
then the coordinate system is rotated through the set angle in the new zero. The angles of
rotation set are not deleted by program end (M02, M30), program abort or switching the
control OFF and then ON again.
Programmable coordinate rotation
The rotation is activated by G58/G59 under address A in the part program. A zero offset can
also be contained in the command. If a zero offset and a coordinate rotation are programmed
under the programmable coordinate rotation, first the zero offset is performed and then the
coordinate system is rotated through the set angle in the new zero.
If several rotations (if necessary combined with zero offsets) are set, the following coordinate
system is always based on the previous one. This also applies to a combination of settable
and programmable rotations.
Programmed angles of rotation can be programmed in absolute or incremental dimensions.
They are deleted by program end (M02, M30), program abort or switching the control OFF and
then ON again.
