Caution
The drive assembly must only be exchanged by or in consultation with the machine
manufacturer!
Drives that you receive in exchange and new drives are already partitioned and formatted.
The HeROS operating mode and the NC software are installed. The hard disks are normally
equipped with the most recent NC software.
This NC software must be released by the machine manufacturer!
If the latest NC software has not been released by the machine manufacturer or if the
NC software version of your defective control should also run on the replacement control, it
must be loaded. For this purpose you also require support from the machine manufacturer.
Note: Dual-processor controls have loaded Windows.
Move machine to home position (axes, tool changer, tilting head, etc.).
