The following examples for TNC 306 show how the flushing timer may be written in the PLC
program:
L W676 ; Auto Jump Distance (AJD)
X K + 100
= D730
L W678 ; Eroding time (ER)
X K + 100
= D734
L M2621 ; Request flushing

4.7 Eroding parameters
In order to control the generator as required, the TNC stores appropriate data as eroding parameters.
Machine parameters MP2199 defined whether these eroding parameters are stored as Q-
parameters in the NC program or in the form of erosion tables.
MP2199 Enable erosion tables
0 = Tables not active
2 = Tables active
