GENERAL SPECIFICATIONS

Connection

Internal bus: Via the Installation Base (model: R3-BSx)

Input, Output: M3 separable screw terminal

(torque 0.5 N·m)

Internal power: Via the Installation Base (model: R3-BSx)

Screw terminal: Nickel-plated steel

Isolation: Input 1 to input 2 to internal bus or internal power

Alarm output: Two outputs per channel available; setpoints

are programmable for the speed or the position data by

using the R3CON PC Configurator software.

DIP switch settings:

•Input range

•Count Mode

•Alarm Contact Form

•Start Count

(Refer to the instruction manual)

RUN indicator: Bi-color (red/green) LED;

Red when the bus A operates normally;

Green when the bus B operates normally;

Amber when both buses operate normally.

ERR indicator: Green LED turns on in normal operating

conditions.

Low-end cutout: 0.1 %

Reset input: Position data reset to ‘0’ when the external

contact is closed. (Reset count can be changed using the

R3CON PC Configurator software.)
