6. Machine parameters
The TNC 150 is adapted to the machine via machine parameters.
Machine parameters can be split into the following groups:
1) Machine parameters either determined by the machine design or freely determined parameters.
2) Machine parameters which are optimised during commissioning of the machine (e.g. output ramp
characteristics)
3) Machine parameters related to the PLC (e.g. PLC-counter preselect value)
With the first group, the parameters can be determined in advance with the correct values. The second group
has a list of predetermined temporary parameters. The third group is programmed into the TNC 150 according
to the corresponding list as long as the PLC-standard prograrn is not changed.
The following procedure is followed for machine commissioning:
1) Determination of the parameters of the first group (see s,ection 6.1)
2) Filling out of complete parameter list in the sequence demanded by the TNC 150 (see section 9)
3) Entry of parameters into the control (see section 8.1-3)
4) Optimisation of temporary parameters as per check-list (see section 8)
