10.5.7 Parameterization of a 2nd measuring systems with ADI4
A maximum of 2 measuring systems can be configured for one machine axis. If
direct connection of the 2nd measuring system to the associated drive module
is not possible, an ADI4 module can be used for this purpose.
Note
For detailed information on measuring systems that can be connected to the
ADI4, please refer to:

Section: Hardware Description
The sample configuration below illustrates the general procedure for configuring
the NC for a 2nd measuring system of a machine axis connected via ADI4. The
following assumptions are made:
 NC
2 measuring systems should be parameterized for the 1st machine axis.
– 1st measuring system: Motor measuring system of drive
– 2nd measuring system: Direct measuring system
 Drive
A SIMODRIVE 611U 1 axis module with connection option for a measuring
system (motor sensor) is used as a drive.
 ADI4
The 2nd measuring system is connected via the sensor interface of the 1st
axis of an ADI4 module (generally, connection is possible to any axis of the
ADI4 module)
The associated configuration is shown in Fig. 10-14.
