1. Overview

️· Product: CUI AMT11 series modular incremental encoder
️· Function: Measures rotational position and velocity. Uses a serial UART interface for configuration and diagnostics.
️· Key Features: Modular design, serial interface (115200 baud), designed for use with the AMT Viewpoint™ application.
️· Warranty: 1-year limited warranty (details on CUI website).
️· Important Disclaimer: Not authorized for critical components in life support systems.

2. Assembly Procedure (Step-by-Step)

This is the most detailed procedural section. Here's a summarized version of the steps:

1. Step 1: Use Tool A: Insert Tool A as a spacer defining distance to the mounting surface.
2. Step 2: Sleeve & Adaptor: Slide a Sleeve over the shaft, then slide the Shaft Adaptor over the sleeve.
3. Step 3: Press Fit: Use Tool C to press the Shaft Adaptor onto the sleeve, ensuring spline alignment.
4. Step 4: Base Centering: Align Tool C with the flange on the Base, slide the Base and Tool C onto the motor.
5. Step 6: Top Cover Placement: Snap the Top Cover onto the Base, aligning the Shaft Adaptor teeth with the hub grooves. (Limited to 3 mounting/removal cycles due to base fatigue.)
6. Step 2: Secure Cover: Press on the Hub with Tool C to ensure snaps are fully engaged.
7. Step 5: Ensure free rotation of the Shaft Adaptor, Sleeve, and Rotor Hub.

3. Serial Interface

️· Purpose: Used for encoder configuration, programming, diagnostics, and index alignment via AMT Viewpoint™.
️· Command `0` (hex: 0x30): Zeros the encoder and sets the index. This position is stored in non-volatile memory.
️· Command `Q`: Restarts the encoder.
️· Settings:
- Baud Rate: 115200
- Data Bits: 8
- Parity: None
- Stop Bits: 1
- Start Bits: 1
️· Pins:
- TX_ENC+: Encoder transmits serial data. Connects to the receiver input of the UART.
- RX_ENC+: Encoder receives serial commands. Connects to the transmitter output of the UART.
- MCLRB: Used for reprogramming with the AMT Viewpoint™ application (not required for basic serial commands).
