1756-M02AE Functional Description  

The Allen-Bradley 1756-M02AE is an advanced analog encoder module designed for motion control applications. This module supports two axes and provides quadrature-position feedback, making it suitable for controlling drives or actuators that require a +/- 10V velocity or torque reference input. The 1756-M02AE ensures that the actuator accurately follows the desired motion profile by using feedback from a quadrature encoder input. It can interface with various rotary and linear transducers that use quadrature-output.

1756-M02AE advanced analog encoder module is compatible with several ControlLogix chassis, including models like the 1756-A4, 1756-A7, 1756-A10, and others. It requires an RTB (Removable Terminal Block) such as the 1756-TBCH or the 1756-TBS6H for proper installation. The 1756-M02AE features a fast loop update rate of 500 microseconds for position and 250 microseconds for velocity, with a torque loop bandwidth of 106 Hz. The module’s digital position and velocity servo loop is controlled by a nested PI algorithm.

In terms of input, the Allen-Bradley 1756-M02AE Analog Encoder (AE) Servo Module accepts incremental AB quadrature encoder signals, with a maximum encoder rate of 4 MHz. The encoder mode is 4X quadrature, and it has a position range of +/- 1,000,000,000 encoder counts. The module draws 700 mA at 5V DC and consumes 3.63 W of power, with a power dissipation of 5.5 W. Its electrical interface is optically isolated, providing protection against electrical noise and interference.

The 1756-M02AE Controllogix 3 Axis Sercos Servo Module also includes features such as home limit switch inputs, drive fault inputs, and drive enable outputs. This module offers flexibility in motion control, providing both open-loop and closed-loop operation, with compatibility for up to 32 axes when used with additional modules. It is ideal for applications requiring precise analog control and feedback.
