A character matrix must always be 15 lines in height and 16 columns in width. It must be
identified with a symbolic name. A period "." in the matrix definition stands for the background
color and a hatch mark "#" stands for the foreground color. CHINESE.TXT is generated before
programming through a dialog number under the code number 105296.
Example:
Content of CHINESE.TXT:
...
33: CHR_E,CHR_R,CHR_R,CHR_O,CHR_R ;comment optional
...
45: ;comment optional
...
This means that the error message no. 33 is shown with the characters CHR_E, CHR_O and
CHR_R from the customized character set. Error message no 45 is shown as control-internal
message, since no character is defined.
• New NC blocks EL CALL (ELECTRODE CALL) and WP CALL (WORKPIECE CALL).
Both NC blocks EL CALL and WP CALL can be activated for editing and execution through MP
7241 (0=disabled, 1=enabled). With EL CALL and WP CALL, an automatic handling system can
be used to load electrodes and workpieces onto the machine and remove them. The changing
process is controlled by the PLC.
EL CALL functions like TOOL DEF with compensation and TOOL CALL
The electrode offset data (D628 ... D640) are always applied in the X/Y plane depending on the
current C position, regardless of a programmed tool axis. A compensation of the C position on
the basis of a C offset must not be included in this matrix rotation.
Example: C offset 10.0
L X 1 Y 0 C +30.0 R F M; positioning of C to 40 Rotation by 30
The tool axis serves also for the determination of the rotational plane for the Cycles 7 and 10 if
the coordinate system is to be rotated.
The effect of WP CALL is to:
- Set the tool axis to Z
- Rotate about the Z axis to 0 (the plane has been rotated)
- Set the datum in X/Y/Z to values from the PLC, followed by a rotation about the Z axis to a
value from the PLC
