Product Overview; Overview; Features; System Confi Guration - Magnescale Ru74 Anleitung

1. Product Overview

1-1. Overview

Th is product is a compact, high-accuracy rotary magnescale that outputs position signals for machine
tools and other equipment requiring high-accuracy positioning.

1-2. Features

In addition to being a magnetic detection system, this product has a unit shape that enables easy installation
and provides superior environmental resistance from condensation and other eff ects.
Because of its extremely slim design (max. 42 mm), less space is taken up when installing in equipment.

1-3. System Confi guration

1-3-1. RU74

RU74 has an interpolation circuit built into the rotary magnescale and is an A/B quadrature signal output
model.
Th e maximum response revolutions vary based on the minimum phase diff erence time setting value of
the output signal.

1-3-2. RU77

RU77 has an interpolation circuit built into the rotary magnescale and is a serial communication model,
compliant with absolute serial communication specifi cations, that enables connection to a controller.
