Characteristics of coordinate rotations
• Coordinate rotations are channel specific.
• Coordinate rotations are active in the current plane.
• Coordinate rotations are suppressed modally if G53 or @706 was programmed.
• Circular interpolation must not be programmed immediately after coordinate rotation.
• If cutter radius compensation is active the angle of rotation can be changed but not the
position of the coordinate zero.
• If an angle of rotation is changed with @ commands while G54 ... G57 are active, @715
must first be programmed. If the settable zero offset is also changed, the command @714
is to be used. Commands @714 or @715 must be in a block of their own.
• Block search or program start must always begin at a block containing all the required
information. This especially applies to shortened block notation (i.e. only those axes are
programmed which are to move).
• If a coordinate rotation and a zero offset are active, neither a transition to another
coordinate rotation or zero offset nor a plane change are permitted.
