AEAT-86AD 14/12 Bit Multi-turn Encoder Module with Built-in Controller

Data Sheet

The AEAT-86AD provides all functions as an optoelectronic mechanical unit in order to implement, with single turn absolute encoder, an absolute multi-turn encoder with a combined capacity of up to 30 bits at extended temperature.

The unit consists of an LED circuit board, a phototransistor PT circuit board, and gear train arranged in between the PCBs.

The built-in controller combined positional information from single turn absolute encoder and multiturn absolute encoder. It provides control inputs and signal outputs to application end. The integrated RS-422 differential line driver output and line receiver are for noise immunity in transmission line.

Specifications

The multi-turn unit is available in the following versions:
• 12-bit solid shaft with Binary output code
• 14-bit solid shaft with Binary output code
• 12-bit solid shaft with Gray output code
• 14-bit solid shaft with Gray output code
• Optical, absolute multi-turn assembly with max. Ø55 mm and typical height mm.
• Operating temperatures of -40°C to +125°C
• Mechanical coupling by means of gear wheels with
module of
• Operating speeds up to 12,000 rpm
• A 2x4-pole pin strip for power supply and signal
• Integrated RS422 line driver and receiver
• Major component of Multi-turn housed encoder
• Cost effective solution for direct integration into OEM
• Immediate position detection on power up

Block Diagram and Detailed Description

Figure Block Diagram

GENERAL

MSBINV

AEAT-86AD Multiturn Encoder Module is integrated with a controller. The controller provides data synchronization between Single Turn Absolute Encoder Module i.e. AEAS7X00 and basic multiturn encoder module. Its combines the serial data from both modules into combined nMT + nST bit resolution to application end.

The most significant bit MSB will always be sent first to DATA+.

With integrated RS422 line driver and receiver, the differential data transmission is compatible with EIA standard RS-422.

SRCLK+ and SRCLK -

SRCLK input pins are used to clocked out the serial outputs data through the DATA pins. Lapse time between words or subsequent data frame must be 40 µs or longer for proper data transmission.

The MSB can be inverted counting direction by using MSBINV.

STROBE

STROBE output pin can be used to determine whether the data is locked or changing. It is high when date is locked, but low when data is changing.

CONNECTION TO AEAS-7X00

Besides VDDA, VDD and GND of AEAS-7x00 need to be connected to the Multiturn Encoder Module, data and control i/o pins also need to be connected and soldered, i.e. NSDOUT, N2SCL, N2NSL and N2DIN

NOTE nMT = resolution of multiturn module nST = resolution of single turn module

DATA+ and DATA -

DATA output pins provides positional information via
synchronous serial interface, which consists of nMT bit of serial data from multiturn module and nST bit of serial data from single turn module.
