The NX2A4E2 (continued)
As briefly described above, NX2A4E2 can be programmed to accept multiple types of resolver based trans-
ducers:

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.

Redundant Resolver Transducers -
This type of transducer has two
resolvers that are geared 1:1 with the input shaft. Examples of a redun-
dant resolver transducer are the HTT-20-1 and HTT-400-1A-J/J from
AMCI. These transducers are typically used in systems that require
redundant controls for safety or high availability. To the NX2A4E2,
these transducers appear as two single resolver, single turn, transducers.

Dual Resolver Transducers -
This type of transducer has two resolvers
in the transducer package that are geared in such a way that the trans-
ducer yields a high resolution absolute position over multiple turns. As
shown in figure R1.1 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.
The NX2A4E2 accepts programming information and reports position, veloc-
ity, and error information over the network connection. This connection means
that you do not have to be physically near the NX2A4E2 while configuring it.
All configuration and setup data is sent from your host system over the net-
work connection. This allows you to:

Configure the NX2A4E2 from anywhere

Store multiple setups on your machine

Copy setup data from one machine to another

Design custom HMI interfaces for configuration and setup that can sim-
plify machine training, startup, and repair.
