Mixed Data Formats
The NX2A4E2 allows you to work with up to four single resolver transducers, up to two dual resolver trans-
ducers, or one dual resolver transducer along with up to two single resolver transducers.
Output data is used to program the channels and preset the transducer position values. Only one channel can
be programmed at a time, so the description of the two formats is straight forward.
If the NX2A4E2 is programmed for a dual resolver multi-turn transducer, and either of the two
input channels is later programmed as a single resolver channel, then both of the channels of the
dual resolver multi-turn transducer input will be re-programmed with the single resolver data.
For example, if channels 3 and 4 are programmed as a dual resolver multi-turn channel, and
channel 4 is later programmed as a single resolver channel, then channels 3 and 4 both become
single resolver channels and the programming for channel 4 is also applied to channel 3.
Input data is broken down into four word blocks for single resolver channels and eight word blocks for dual
resolver channels. When channel 1 is programmed as a single resolver channel, then the stop time on that
channel can be monitored. In this case, two additional words, the Stopping Tine, and Brake Applied Position,
are available after the channel data blocks.
Output Data Formats
Single Resolver Data Format
Figure R2.1 below shows the format of the output data when programming the module to operate with single
resolver transducers. Only one programming bit in the Command Word can be set at a time. Therefore, when
programming the NX2A4E2 to interface with four single resolver transducers, four programming blocks are
needed.

This reference chapter details the input and output data formats used to commu-
nicate with the NX2A4E2 in single turn and dual resolver, multi-turn applications.
