Sequence in AUTO mode
As a result of the changing load, for direct drives (e.g. torque motors) it may be necessary to
tune the axis involved for each new workpiece size or clamping device.
Standard cycles (CYCLE751...759) are available, that machine OEMs can use in a
manufacturer cycle. The automatic servo tuning can be parameterized and started using the
cycles. The previous settings and results from the automatic servo tuning can be employed,
using SINUMERIK Operate. The machine manufacturer provides the machine operator with a
manufacturer's cycle, which includes the appropriate commands. This means that after
retuning, an end user can insert a manufacturer's cycle in his part program, which performs the
tuning and selects the appropriate data sets. The part program does not have to be interrupted
for the retuning.
The following settings must be made by the machine manufacturer so that the cycle call for the
automatic servo tuning from the part program functions at the end user.
● The instance of SINUMERIK Operate on which the cycles are executed has been selected.
● The XML files with the appropriate tuning settings for the respective axis, which are required
by the cycles, are available.
● The manufacturer cycles are available, and when required a parameter set switchover is set
up.
Additional information about the cycles and a description of the syntax are provided in Chapter
"Automatic Retuning" in the "Axes and Spindles
