Overview Manuals Specifications Application Operating Specifications Control Characteristics

Features:

  • Encoder feedback support for precise single-axis motion control in ControlLogix systems.
  • Three diagnostic indicators (OK, FDBK, DRIVE) provide real-time status of module, feedback, and drive states.
  • NVS update support with fault reset capability using Motion Axis Fault Reset instruction.
The 1756-M02AE/A’s three indicators—OK, FDBK, and DRIVE—tell you exactly what’s wrong. OK shows module health, FDBK tracks encoder feedback, and DRIVE shows drive state. No guesswork, no extra tools. Green means normal, red means fault. Flashing? Check configuration or recoverable faults.

When a fault occurs, check the servo fault word to find the source. Correct the problem, then execute Motion Axis Fault Reset. For drive shutdowns, use Shutdown Reset. If the module stays solid red after restart, replace it. Clear steps, no mystery.

Updating nonvolatile memory? The OK indicator flashes red during the update—normal behavior, not a fault. Once complete, the module returns to steady green. You’ll know exactly when the update is in progress and when it’s done.

The 1756-M02AE/A Allen-Bradley Analog Motion Modules may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Precision Positioning System: Utilizes incremental AB orthogonal encoder feedback for closed-loop control.
  • Multi-axis Synchronous Control: Each module controls two axes; a single controller can be expanded to up to 32 axes, suitable for complex automated production lines.
  • Industry Applications: Widely used in power plant DCS monitoring, cosmetic/pharmaceutical constant flow control, intelligent flatbed furnaces, and automated production lines in papermaking, printing and dyeing, etc.
  • Physical Installation: Installed in a ControlLogix 1756 rack, requiring the use of a 1756-TBCH or 1756-TBS6H removable terminal block.
  • Isolation Protection: Optical isolation is used between the channel and the backplane, enhancing stability in harsh electrical environments.
  • Resolution: 16-bit DAC output ensures smooth analog control signals.
  • Feedback Monitoring: Features Registration Input for precise position and timing.
  • LED Indicators: Front panel features an OK indicator. A solid green light indicates normal operation, while flashing may indicate standby or firmware update.
  • Software Integration: Configurable via Studio 5000 (formerly RSLogix 5000), supporting real-time modification of motion parameters and troubleshooting.
Description
The 1756-M02AE/A is a servo module for Allen-Bradley ControlLogix systems, providing precise motion control for single-axis applications. It supports encoder feedback and includes diagnostic indicators for OK, FDBK (feedback), and DRIVE status. The module requires proper configuration and axis tag association before operation. 

For fault diagnosis, the 1756-M02AE/A uses color-coded indicators. A flashing green FDBK indicator means the servo loop is inactive; steady green indicates active control. A flashing red FDBK indicator signals that the servo loop error tolerance has been exceeded, while a solid red indicates an encoder feedback fault. 

The 1756-M02AE/A supports nonvolatile memory storage (NVS) updates. During an NVS update, the OK indicator flashes red; after completion, normal operation resumes. The module also includes a servo fault word for error source identification. Faults can be cleared using the Motion Axis Fault Reset instruction.

This module solves the pain point of integrating motion control into ControlLogix systems with clear visual diagnostics. The 1756-M02AE/A’s indicator system allows operators to quickly identify whether issues are related to configuration, feedback, drive state, or encoder faults, reducing downtime and simplifying troubleshooting.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What does a steady green OK indicator mean on the 1756-M02AE/A?
It means axis data is being exchanged and the module is in normal operating state.
What should I do if the FDBK indicator is solid red?
A solid red FDBK indicator means an encoder feedback fault has occurred. Check encoder and power connections, then use Motion Axis Fault Reset.
How do I clear a servo fault on the 1756-M02AE/A?
Clear the servo fault condition using the Motion Axis Fault Reset instruction after correcting the source of the problem.
What does a flashing red DRIVE indicator indicate?
The axis drive output is in shutdown state. Check for faults, execute Shutdown Reset motion instruction, and resume normal operation.
