3/97 TNC406/TNC 306 Update Information No. 11
1-9
The coordinate system is first shifted in X/Y/Z and then rotated about the Z axis. The rotation
results in an automatic shift in C.
The control takes the data for the two blocks from the PLC. When EL CALL or WP CALL is
executed the programmed name and an identifier are transferred to the PLC. Then the NC sets
the S strobe (M2044). The PLC can then decide which of the two blocks is to be executed in
order to operate an EWIS robot system, for example. After the electrode, workpiece or pallet has
been changed, the data of the electrode or workpiece must be available in the PLC in the word
markers starting with D628. Then the acknowledgment marker M2481 must be set in the PLC
for a PLC scan. The NC takes the EL CALL and WP CALL data from the PLC and resets the
strobe M2044. Now the corresponding calculations are made (compensation/shift/rotation) and
executed. The datum-shift data of the workpiece are always relative to pallet datum, which must
agree with the manual preset.
It is recommended that after an EL CALL/TOOL CALL with a block L X... Y... C... the
electrode be moved to a compensated position for further machining, since the electrode
shifting movements are rotated depending on the C position. This means that for all erosion
processes in which the electrode must move in the proper direction, the compensated C
position must first have been reached.
