NX3A1X Specifications Rev 1.0 Networked Resolver PLS Module Module Overview This AMCI Nexus module is a single resolver input programmable limit switch module that communicates on a network. The available networks, along with the corresponding AMCI part numbers, are shown in the following table. Network ControlNet DeviceNet Ethernet Profibus Modbus TCP/IP Each module accepts a brushless resolver based transducer for position feedback and generates up to 16 limit switch outputs based on the transducers’ position and velocity. The NX3A1X module has several modes of operation that allow you to enable or disable the outputs based on discrete inputs and the speed of the machine. The NX3A1X module has two modes of operation, Independent Mode and Group Mode. While in Independent Mode, each output is independent of the others and has a corresponding input that is ANDed with the output. When in Group Mode, the outputs are combined into groups. The NX3A1X module has a maximum of six groups. Each group is assigned an Operating Mode that controls how the outputs fire. At this time, there are a total of seven Operating Modes. These Operating Modes are geared towards high speed packaging and assembly machines. This unit has sixteen I/O points. Eight of the outputs and all sixteen inputs are located on the Nexus module itself, and the remaining eight outputs can be located on an external relay board. The inputs can be programmed to be used either high true or low true, and provide ANDing functions and group control. The inputs are divided into two groups of eight, and can be used as either sinking or sourcing inputs. The status of the 16 inputs is also reported over the Network. Each of the outputs has 8 On/Off setpoints, and can be programmed to operate in normal, timed, or pulse mode. The outputs can be ANDed with an input or with a motion detector, and can also be forced ON or OFF from the PLC. The outputs will turn off when there is a transducer fault condition, even if it is a clearable transducer fault. The status of the 16 outputs is reported to the PLC over The Network. Outputs should not be programmed on the fly. The module contains a non-volatile memory so all of the setup data and On/Off setpoints will be saved on power down. Because the non-volatile memory is a battery backed RAM, all of the parameters can be changed often without damaging the module. 20 Gear Drive, Plymouth Industrial Park, Terryville, CT 06786 Tel: (860) 585-1254 Fax: (860)584-1973 E-mail: sales @amci.com

NX3A1X Specifications Rev 1.0 Networked Resolver PLS Module Wiring A CTL-(x) cable, where (x) is the length in feet, is used to connect an AMCI single resolver transducer to an NX3A1X module. If you order a CTL-(x) cable from AMCI that is less than 100 feet long, we ship a cable that is made from a Belden 9873 or equivalent. If you order a CTL-(x) cable that is over 100 feet, we ship a cable made from a Belden 9730 or equivalent. One end of the CTL-(x) has a Bendix MS connector that mates with all AMCI single resolver transducers that have a connector. The other end is pigtailed at the factory...
