  • Page 10: Overview

    1. OVERVIEW 1. OVERVIEW 1-1. Overview The AB935N module is an ABSOCODER converter for the TC-net I/O System of the Toshiba Corporation Unified Controller nv Series. Combine the module with a linear type ABSOCODER sensor (VLS-8SM) to have the detected position data converted into binary codes.

  • Page 11: Terminology

    1. OVERVIEW 1-3. Terminology (1) ABSOCODER "ABSOCODER" is a generic name referring to the type of sensing device that detects rotational and linear displacement as well as speed and acceleration in an absolute format and outputs them digitally (or analogously). "ABSOCODER" comprises a detection unit that converts displacement into a variation in magnetic resistance and a conversion unit that inputs an alternating-current energization signal into the detection unit and then issues an absolute-format data according to the output signal returned from the detection unit.
  • Page 12 1. OVERVIEW (3) Semi-absolute format The AB935N module detects the machine position in a semi-absolute format. In the semi-absolute format, “standard pitch” of the sensor rod is detected in absolute value. (Absolute detection range) Furthermore, the pitch is counted by the software. 1 pitch 2 pitches 3 pitches...
