Absolute – EnDat

Proprietary serial communication protocols for absolute encoder feedback developed by Heidenhain. Transmitted information includes data plus separate Sin/Cos signals. Benefit Absolute feedback gives the drive enough information to start sinusoidal commutation without the need for Hall Sensors or “wake-and-shake” routine ADVANCED Motion Controls’ Capabilities 8-Wire interface plus two wires for the optional reference mark 38.4 Absolute – EnDat

Absolute – Hiperface

Proprietary serial communication protocols for absolute encoder feedback developed by Stegmann. Transmitted information includes data plus separate Sin/Cos signals. Benefit Absolute feedback gives the drive enough information to start sinusoidal commutation without the need for Hall Sensors or “wake-and-shake” routine ADVANCED Motion Controls’ Capabilities 6-Wire interface plus two wires for the optional reference mark 4 Absolute – Hiperface

Incremental Encoder – TTL

The most common encoder type, these encoders use discrete 0-5V lines for position increments. TTL encoders typically have two channel (A & B) for position information plus an Index channel. Quadrature is used to increase the resolution by 4x. Benefits Tried and true technology that is readily available from many encoder manufacturers Standard feedback on Incremental Encoder – TTL

Incremental Encoder – 1Vp-p

Incremental encoder that uses Sin/Cos signals rather than discrete 0-5V lines for position increments. Benefit This type of encoder makes it possible to interpolate between lines to greatly increase the encoder resolution ADVANCED Motion Controls’ Capabilities Interpolation of the 1Vp-p Sin/Cos up to 2048 counts per cycle. A 1000 line encoder with 2048 interpolation would Incremental Encoder – 1Vp-p

Auxiliary Encoder

Most encoder-feedback systems have a single encoder mounted on the motor for velocity and/or position feedback. In some systems, however, a secondary (or auxiliary) encoder is placed directly on the load for dual-loop control.   Why would you need dual-loop control? Auxiliary encoders are especially useful in applications with a load that’s not directly driven Auxiliary Encoder

Absolute – BiSS-C

Open serial communication protocol for absolute encoder feedback developed by IC-Haus. BiSS stands for Bi-directional Synchronous Serial Interface. The signal is “data only”, meaning there is no extra Sin/Cos signal for the drive to process. Benefits Absolute feedback gives the drive enough information to start sinusoidal commutation without the need for Hall Sensors or “wake-and-shake” routine Encoder position Absolute – BiSS-C
