INTRODUCTION
TO THE
ANA2
The ANA2 (continued)
The ANA2 can be programmed to accept two types of resolver based transducers:
 Single Resolver Transducers - This type of transducer has a single
resolver in the transducer package. This type includes transducers that
yield an absolute position over a single turn, such as our HT-20, 
HT-400, H25, and R11 product lines, and transducers that include an
integral gear train between the input shaft and the resolver so they can
yield an absolute position value over multiple turns. An example of this
type of transducer is any member of the HT-20-(x) line from AMCI.
 Dual Resolver Transducers - This type of transducer has two resolvers
in the transducer package that are geared in such a way that the transducer yields a high resolution absolute position over multiple turns. As
shown in figure 1.2 to the right, there are two types of dual resolver
multi-turn transducers. One type uses a vernier gearing, where the two
gears differ by one tooth. Examples of this type of transducer are the
HTT-20-100, HTT-20-180, HTT-20-1000 and HTT-20-1800 transducers
from AMCI. The second type uses a gear reduction between the fine and
coarse gear so that the coarse gear completes one rotation for multiple
turns of the fine resolver.
A third type of transducer is the redundant dual resolver transducer, such as the HTT-20-1 and HTT-400-1 from AMCI. This
type of transducer has two resolvers that are geared 1:1 with the
input shaft. They are typically used in systems that require
redundant controls for safety or high availability. To the
ANA2, these transducers appear as two single resolver transducers so this transducer type is treated as such in this manual.
The ANA2 accepts programming information and reports position, velocity,
and error information over the network connection to the AnyNET-I/O stack.
This connection means that you do not have to be physically near the ANA2
while configuring it. All configuration and setup data is sent from your host
system over the network connection. This allows you to:

Design custom HMI interfaces for configuration and setup that can simplify machine training, startup, and repair.

Master/Slave Module
Some applications require position feedback to two different controllers. One example of this is feeding a
resolver into an ANA2 as well as a servo drive controller. Previously, many of these applications required the
use of a redundant dual resolver transducer, but the programmable parameters of the ANA2 will now allow
you to use a single resolver in most applications. This is accomplished by configuring the ANA2 as a Slave
module.
All ANA2 modules ship as Master modules and generate their own reference voltages. You change an ANA2
to a Slave module by changing a jumper on the front of the unit and programming a parameter in the network
data. External wiring is then used to connect the resolver master to the ANA2 slave module. The ANA2
reads the reference voltage from the resolver master and uses this data to properly decode the resolver position. Note that the ANA2 can interface with one or two resolvers while acting as a Slave module. The only
restriction is that the reference voltage and frequency must be the same for both resolvers.
