11.5.7 Parameterization of a 2n d 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:
References: /ADI4/ Analog drive interface for four axes
Section: Hardware Description
The following parameterization example illustrates the basic procedure for para-
meterizing the NCK for a 2nd measuring system of a machine axis connected
via ADI4. It assumes the following:
S NCK
2 measuring systems are to be parameterized for the 1st machine axis.
-- 1st measuring system: ”motor measuring system” of the drive
-- 2nd measuring system: ”direct measuring system”
S Drive
SIMODRIVE 611U 1 axis module is used as the drive with a connection op-
tion for a measuring system (motor encoder).
S ADI4
The 2nd measuring system is connected via the encoder interface of the 1st
axis of an ADI4 module. (Connection is possible via any axis of the ADI4
module.)
The configuration is shown in Fig. 11-12.
