Parameterization of a 2nd measuring system with ADI4

Up to 2 measuring system can be parameterized for a machine axis. If it is not possible to
connect the 2nd measuring system directly to the associated drive module, it is possible to
use a ADI4 module.
Note
Detailed information about the measuring systems that can be connected to the ADI4 is to
be found in:
