Absolute Encoder

Power-off memory

Mechanical gear multi-turn

without internal battery

Single Turn

For a clock with a “minute hand" : it can only record the position of the"minute hand" within the 0~360° rotation cycle.

For example:

with a single-turn encoder, when it rotates to "50", after power off and then powering back on, you can directly read the angle value.

The mechanical structure of a single-turn encoder can achieve continuous rotation.

Due to being able to retain data only within a single revolution after a power outage, it is defined as a single-turn encoder.

Normal mode:

When more than one lap is completed, the value resets to 0 and starts counting again.

Multi-lap mode:

In a continuous power supply situation, it can count multiple laps.

Multi-Turn

A clock with"minute hand + hour hand":

It can provide feedback on the position of the"minute hand" within the 0-360°cycle. It can also provide feedback on the numberof rotations made by the "minute hand' through the "hour hand".

For example:

A 24-turn encoder can be turned to 2 turns and 50 degrees, and can be read directly after power-off and power-on. When it exceeds 24 turns, the value will start counting from 0 again.

The mechanical structure of a multi-turn encoder allows for continuous rotation.

It can remember the data within a single turn and the number of turns even after a power outage. So it defined as multi-turns

Interface(RS485/RS232/CANbus/CANopen/SSI):

Notes:

The yellow wire is a functional wire. It can be used for setting encoder zero position or restoring encoder factory settings.

When the encoder is in normal use, the yellow wire should be suspended and not be connected.

Three simple ways to set absolute encoder to zero position?

Method 1. Connect yellow wire to ground (black wire) more than 100mS. After set zero, please separate the yellow and black wire.

Method 2. After right connected the wires according to the wiring definition. send set zero position command according to the user manual.

Method 3. Use the host computer software provided by our company (BriterEncoder).

How to restore the absolute encoder to factory settings?

Step 1, After power off, connect the yellow wire to the black wire.

Step 2, power on, and hold for two minutes.

Step 3, power off, then separate the yellow wire from the black wire. now the rotary encoder ha restored to factory settings.

Description

Analog Communication

Direct output values for current, voltage and resistance

The voltage, current and resistance signals of the encoder are collectively referred to as analog signals, and analog signals are widely used in industrial control systems in the automation industry. For the site environment is complex, interference is more serious or the need for long-distance transmission of special occasions, it is recommended that priority be given to electric analog sensors.
