Note: 1. Use of set line (gray)

When the set line (gray) touches Vcc for more than 1 second, the current data of the encoder becomes the set value (zero point)

Use of direction lines (blue)
Connect the blue wire to a high level (that is, the encoder power supply is positive), and the encoder output value is counterclockwise (CCW).

Connect the blue line to low level (or leave it in the air), the encoder output value is clockwise (CW)

Mechanical dimension drawing
Clamping synchro flange (optional for cable output or plug output)

Synchronous flange/servo flange (cable output or plug output optional)

Blind Hole/Half Through Hole Flange (Cable output or plug output optional)

Absolute encoder parameter setting
The encoder is to set the communication frequency, address and resolution of CAN through our company’s special RS485 communication setting software.

The baud rate of RS485 communication is fixed at 115200.

Frame format: 8 data bits, 1 stop bit, no parity, no control flow
