Allen-Bradley 1756-M02AE ControlLogix Servo Module

1.General Description

The Allen-Bradley 1756-M02AE ControlLogix Analog Motion Servo Module is a high-quality motion control device.  Part of the ControlLogix family by Allen-Bradley. Designed for precision position and velocity loop motion control, it provides advanced motion capabilities for demanding industrial applications.

This closed-loop module is perfect for systems that need accurate positioning. It handles registration input and gets position feedback from encoders or other devices.

The 1756-M02AE supports both open-loop and closed-loop setups. It allows smooth control of up to 32 axes in coordinated motion systems. This is possible when using multiple modules in the same chassis.

The Allen-Bradley 1756-M02AE Series A Cat Rev G01 provides fast updates for position and speed. This makes it ideal for servo-driven machines that need real-time syncing and precision.
