Insert Tool A as a spacer that defines the distance to the mounting surface. 2. Slide appropriate sized Sleeve over shaft all the way down to Tool A. 3. Slide Shaft Adaptor over Sleeve. 4. Use Tool C to press Shaft Adaptor over Sleeve (ensure Shaft Adapter and Tool C spline alignment) until flush with Tool A. STEP 4 1. Remove Tools A and C. 2. Place Base on motor, with Tool C used as a centering tool. STEP 5 STEP 6 1. Snap the Top Cover onto the Base, carefully observing that the teeth of the Shaft Adaptor align with the grooves in the hub. * 1. Fasten the Base on the motor (Tool C may need to be rotated to allow for some mounting configurations). 2. Remove Tool C. 1. Align Tool C with flange on Base. 2. Slide Base and Tool C onto motor, centering onto the Shaft Adapter. * We recommend no more than three cycles of mounting and removal of the AMT top cover base. Multiple cycles of mounting and removing the top cover can cause base fatigue over time and affect encoder performance. cui.com 1. Make sure the snaps are fully engaged by pressing on the Hub with the reverse side of Tool C. 2. When assembly is finished, the Shaft Adaptor, Sleeve and Rotor Hub should all be flush with the Motor Shaft rotating freely. For more information, please visit the product page. CUI Inc │ SERIES: AMT11 │ DESCRIPTION: MODULAR INCREMENTAL ENCODER date 10/13/2015 │ page 8 of 9 APPLICATION NOTES SERIAL INTERFACE The AMT11 series encoder is designed to operate with a serial UART interface. This interface allows the encoder to be configured and programmed by the AMT Viewpoint™ application. Along with programming, the AMT Viewpoint™ application uses the serial interface for diagnostics and index alignment. Below are instructions on how to use the serial interface for position zeroing. Table 1 Serial Commands Command Action Use 0 This command sends an ascii ‘0’ (hex value 0x30). This zeros the encoder and sets the index at the current angular position. This position is stored in non-volatile memory and will remain present until a zero command is set again or encoder is reprogrammed via AMT Viewpoint™. Q This command sends an ascii ‘Q’ (hex value 0x51). This command restarts the encoder as if it were power cycled. Table 2 Serial Pins Pin Description Connection TX_ENC+ This is the pin that the encoder transmits serial data on. Connect this pin to the receiver input of your serial/UART interface. RX_ENC+ This is the pin that the encoder receives serial commands on. Connect this pin to your serial/UART interface transmitter output. This pin is used to force the encoder into reset for reprogramming via the AMT Viewpoint™ application. Connection of this pin is not required for the above serial commands. MCLRB The serial interface operates at 115200 baud with 8 data bits, no parity, and 1 stop bit, and 1 start bit. This is the standard UART protocol. Data lines TX_ENC+ and RX_ENC+ are high when inactive.
