Module Overview
Utilizing licensed Allen-Bradley interface technology, these Resolver Interface Modules can be added as
expansion modules to Rockwell Automation's MicroLogix 1100, 1200, and 1400 rack systems.
The 1141 is a one channel module that can be connected to one resolver, and the 1142 is a two channel
module that can be connected to either two independent single resolver transducers or a single dual resolver
transducer.
Both the 1141 and 1142 modules have an input that can be configured for stop time monitoring (channel 1
only), to capture the current position, or to offset the current position to a previously programmed preset value
(channel 1 only). This input will operate at either at 24Vdc or 120Vac.
These modules have the additional ability to be programmed to interface to Autotech and standard Gemco
resolvers that have a transformation ratio of 1.4.
Prior to serial number 03180001, only the now obsolete 1141A and 1142A
modules could be programmed to be compatible with resolvers that have a
transformation ratio of 1.4.

These parameters are stored in nonvolatile memory. Therefore, there is no need to configure the 114X after every power up. The nonvolatile memory is an EEPROM that is rated for approximately 100,000 write cycles. -

Page 14: Transducer Type
The Transducer Type parameter exists for dual resolver multi-turn transducers only. This parameter does not exist on 1141 modules or on a channel that is programmed to be used with a single-resolver transducer. The Transducer Type parameter defines the type of multi-turn transducer attached to the module. The 1142 needs this information in order to decode the multi-turn position correctly. -

(Eight 16 bit words sent from the PLC to the 114X module) The 1141 can only be programmed to work with a single resolver transducer. The 1142 has two possible configurations. It can be configured to use two Single Resolver Transducers- which includes the HT-20, H25-XX, and the HT-20-X series- or one Dual Resolver Multiturn transducer, which includes the HTT-20-X series. -

4. The Disable Channel 2 bit only exists on 1142modules and in the channel 2 single resolver setup word. This bit is reserved on 1141 modules and in both the channel 1 single resolver setup word and the dual resolver setup word of 1142 modules. - Page 22 11. Programming the Resolver Type parameter on either of the channels will affect both channels. If you have to use one AMCI and one Autotech resolver, set the module for AMCI and use a RM-3 reference module between the 114X module and the Autotech resolver.
