What are the uses of this absolute value motor encoder definition? [Copy link]

What are the uses of this absolute value motor encoder definition? What are the uses of +SIN, +COS, REFSIN, REFCOS, TS+, and TS- respectively? I only know the uses of power and Data+ and Data-. Can someone explain the definitions of other pins?

The specification should explain it clearly. After all, not all absolute encoders have the same pins. I have used 16-state ones, which can read 16 states through 4 IO ports. There are not so many pins.

Here are the wiring instructions

The definition of the specific line depends on how the encoder manual defines it.

+SIN, +COS are the solutions for the sine and cosine encoders in the analog encoders

Data+ and Data- should be connected to 485

Other manufacturers have different wiring definitions

SIN COS can be solved by ADC, Data is the communication port

qwqwqw2088 posted on 2024-1-24 20:25 This is the wiring description. The definition of the specific line depends on how the encoder manual defines it. +SIN and +COS belong to the positive and negative in the analog encoder...

This means that the position and speed of the motor can be obtained not only by sine and cosine methods, but also by 485 communication, right?

1. +SIN, +COS: These two pins are the encoder's sine (SIN) and cosine (COS) output signal pins. They provide analog output signals related to the motor's rotor position and can be used to determine the motor's angular position.

2. REFSIN, REFCOS: These two pins are the encoder's sine (REFSIN) and cosine (REFCOS) reference signal pins. They provide analog signals for calibration and reference, usually provided by the encoder's own internal reference signal generator.

3. TS+, TS-: These two pins are the interface pins of the temperature sensor. They are connected to the internal temperature sensor of the encoder and can be used to measure the temperature of the encoder so as to perform temperature compensation when necessary.

Other pins include the power pin (power supply), Data+ and Data- pins (digital communication interface), which have the following functions:

• Power pin: used to provide the working power required by the encoder.
• Data+ and Data- pins: used for digital communication with other devices, such as encoder data transmission using communication protocols such as RS-485 or SSI.
