This module supports two independent axes of motion, allowing the controller to scale up to 32 axes per controller system. It utilizes incremental A\/B quadrature encoder inputs with marker signals to maintain position precision, while providing 16-bit resolution analog voltage signals to drive external servo amplifiers. Integrated optically isolated discrete inputs and solid-state relay outputs provide high-speed auxiliary control functionality for homing or limit monitoring, maintaining continuous electrical isolation up to 50 V.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1756-M02AE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.45 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard 1756 ControlLogix form factor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e6.2 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAxes per Module\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eServo Output Resolution\u003c\/td\u003e\n\u003ctd\u003e16-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (5 V)\u003c\/td\u003e\n\u003ctd\u003e700 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (24 V)\u003c\/td\u003e\n\u003ctd\u003e2.5 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n\u003ctd\u003e50 V Continuous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProfinet and EtherNet\/IP Deterministic Network Connectivity\u003c\/h3\u003e\n\u003cp\u003eThe 1756-M02AE module interfaces with the ControlLogix backplane to participate in deterministic motion control cycles. The module's internal firmware ensures that encoder feedback data is sampled and synchronized with the controller's motion task, providing low-latency command updates. When integrated into networks utilizing EtherNet\/IP, the module provides I\/O density scaling capabilities, allowing motion status and diagnostic data to be shared across the backplane for multi-controller coordination. Firmware flash compatibility must be maintained to ensure proper synchronization between the motion module's command output and the overarching EtherNet\/IP motion profile.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1756-M02AE be hot-swapped while the ControlLogix chassis is powered?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the ControlLogix platform supports Removal and Insertion Under Power (RIUP) for the 1756-M02AE; however, all servo loops associated with the module must be inhibited in the software to prevent uncontrolled motion upon module removal or insertion.\u003c\/p\u003e\n\u003cp\u003eQ: What is the purpose of the marker signal input on the encoder interface?\u003c\/p\u003e\n\u003cp\u003eA: The marker signal (or Z-channel) provides a reference index pulse per revolution, which the module uses to perform precise homing operations and to verify encoder position integrity within the feedback loop.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003ePower down the system if site protocols restrict RIUP operations, or ensure all axes are in a safe, inhibited state before module insertion.\u003c\/li\u003e\n\u003cli\u003eAlign the 1756-M02AE with the chassis slot and seat it firmly into the backplane connector.\u003c\/li\u003e\n\u003cli\u003eTerminate encoder signals and servo drive commands to the required Removable Terminal Block (RTB).
