Resolver Interface Card
High Resolution Resolver
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.
