Notes Make sure that the selected drive (display) corresponds to the connected test
sockets (DACs) of the appropriate drive (module) in the case of 611D signals.
Servo signals (max. 4) can be output by every module – however, the axis name
must also be input.
The analog output must be set again after power on reset.
When 611D signals are output from an

the drive (drive number) which is to be measured must be selected for the output.

It is not possible to save the DAC configuration with "Load/save all" for com-
plete backup, nor is it possible to load a boot file via the File function.
The DAC boot file should be deleted if the DACs are not longer required, in
order to reduce the load on the processor.
It is no longer possible to reinstall the analog output after Power On as these
DACs are active again after Power On.
