Interface Card for A-B SLC500

I/O Chassis

The Series 1746R Resolver Interface Card is a resolver

based unit that incorporates Allen-Bradley licensed

technology for complete compatibility with A-B Series

1746 I/O chassis. The unit monitors machine position

and delivers continuous absolute position data at

12 bit (4,096 count) resolution and RPM data to the

SLC processor.

The Series 1746R Resolver Interface Card is available in

two versions. 1746R-1 is for single axis applications and

uses a single turn resolver. Standard “Turns Counting”

software allows a single turn resolver to be used in

multi-turn applications. The Series 1746R-2 is for dual

axis applications and can use two, single turn resolvers

to monitor each axis independently, or is field config-

urable for use with a single, multi-turn dual resolver to

monitor a single axis for absolute positioning over mul-

tiple revolutions.

Each channel has an auxiliary input that can be field

configured to operate in one of two ways:

1. Reset to Preset. This feature allows you to continu-

ously synchronize position data to the leading edge

of the product or to automatically compensate for

process drift.

2. Brake monitoring in metal stamping applications.

In this configuration, automatic calculation of stop

time and stop angle is transferred to the I/O image

table. In addition, two programmable time limits are

available to monitor maximum stop values: the first

as a potential maintenance warning, and the second

as an error if the press exceeds the programmed

maximum acceptable stop time.
