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.
