Program execution from external source
When complex workpieces are machined, the NC may not have enough memory for the
programs. Using the function "Execution from external source" or "EES (execution from
external storage) enables part programs to be called and executed from an external memory
(e.g. from the hard disk).
Behavior after POWER ON, Reset, ...
The control-system response after:
● Power up (POWER ON)
● Reset/part program end
● Part program start
can be modified for functions, such as G codes, tool length compensation, transformation,
coupled axis groupings, tangential follow-up, programmable synchronous spindle for certain
system settings through machine data.
Subroutine call with M, T and D functions
For certain applications, it may be advantageous to replace M, T or D functions as well as a
few NC language commandsSPOS, SPOSA, by a subroutine call. This can be used, for example,
to call the tool change routine.
Relevant machine data can be used to define and control subroutines having M, T or D
functions. For example, for a gear stage change.
Program runtime/part counter
Information on the program runtime and the part count is provided to assist the machine tool
operator.
The functions defined for this purpose are not identical to the functions of tool management
and are intended primarily for systems without tool management.

Mode group

Mode group
In a mode group, multiple channels if an NC are grouped together to form one processing unit.
In principle, it is an independent "NC" within an NC.
