Note: RS485 signal can be used for encoder settings or as a standard signal output.

Precautions for RS485 communication:

1.The communication speed and transmission distance are contradictory. The higher the speed, the closer the transmission distance, but also the more stable it is, and vice versa.

2.When there is strong external electromagnetic interference, the external setting line needs to be connected to a high level when setting the encoder. However, it is recommended to force a low level after setting to prevent the encoder from suddenly returning to zero due to external interference.

3.When external electromagnetic interference is strong,It is best to use double shielded cables for RS485 wiring.

4.When multiple encoders are connected to the upper computer, it is recommended to distinguish the data returned by each encoder in terms of time when programming the upper computer, as the encoder returns data without parity check.

5.When there is an electric motor in the system, the encoder power supply needs to be isolated from other power sources.

due toThe RS485 circuit is in differential form, with A+and B - both carrying voltage. Prolonged grounding or high voltage can cause damage to the RS485 circuit

RS485 communication protocol description:

Baud rate: 4800bps. 9600bps. 19200bps. 38400bps. 115200bps Frame format:Data bit 8, stop bit 1, no parity check, no control flow.

Modbus communication protocol description:

Baud rate: 4800bps. 9600bps. 19200bps. 38400bps. 115200bps Frame format:Data bit 8, stop bit 1, even check, no control flow

The use of set lines (gray)

When the device needs to find the zero point or recalibrate the zero position, please short-circuit the gray line to the 24V power supply for 3-5 seconds. After reaching the time, please remove the gray line. This is the default zero point position of the encoder.

Programming allows the use of lines (blue)

When setting the mode, connect the blue and brown wires of the encoder together to the positive power supply, and connect the white wire to the power supply ground wire. At this point, the communication rate of the encoder is fixed at 19200bps. In non setting mode, it is recommended to connect the blue and white wires together to the power ground wire during normal operation.
