Absolute Encoder EAS38—RMB User Manual

★Please totally read the following instruction first for proper use of encoder.

주의 : 1. Programming-permit-line (파란색)을 사용하는 방법

When setting the mode: the blue wire of the encoder and the brown wire are connected to the positive power+ together. At this time, the communication rate of the encoder is fixed at 19200bps.

비 설정 모드 : 정상 작동시 청색 전선과 백색 전선을 전원 접지에 연결하는 것이 좋습니다.

2. 리셋 라인 사용 방법 (회색)

리셋 라인 (회색)이 1 초 이상 power +에 연결된 경우, 엔코더의 현재 데이터가 리셋 값이됩니다 (엔코더의 리셋 값은 임의로 설정 가능)

The encoder can also be reset by using the instruction (for specific instructions, refer instance 2)

The Modbus communication protocol description:

Baud rate:. 4800bps 9600bps (default) 19200bps 38400bps 115200bps….

Frame format: 8 data bits, 1 stop bit, even parity, no flow control (Can be customized without parity, please inform when ordering)

Message format

Function code 03H: reads the parameter value

The requests of the master: address/ function code/ the address of the parameter/ the length of the data/ check code

The responses of the slave: address/ function code/the length of the byte /the parameter value/ check code

Function code 04H: read the measured values

The requests of the master: address/ function code/ the address of the data/ the length of the data/ check code

The responses of the slave: address/ function code/the length of the byte /the data information/ check code

Function code 10H: modify the parameter values

The requests of the master: address/ function code/the address of the parameter / the length of the data/ the length of the byte/ the parameter value / check code

The responses of the slave: address/ function code/ the address of the parameter / the length of the data / check code

The communication agreement between master-slave machines:

The master send each frame of data should contain the following information (hexadecimal)

The address of the slave / Function code/ Information words/Check code

Slave address (1 byte): the Slave’s number of equipment. From the address of the slave, the master identify communication equipment. That set by the user address, slave will receive information sent by the master. In a Modbus network, each of the slave must have a unique address code, and can only respond to meet address code from the slave.

Function code (1 byte): The function code sent by the master to inform the slave what task to perform.

Information word (N bytes): Including different addresses of the data, the length of the data, and the data’s information between the communications of the machines.

Check code (2 bytes): Because used to detect data communication is error, using cyclic redundancy CRC16 check.

Instance

1. Reset command

           Host sends 01H 05H 00H 00H check code

Slave reply: 01H 05H 00H 00H check code

1. Read the measurement data commands
   Host sends 01 04 00 01 00 02 20 0B
   Note: 01 is encoder address , 04H is function code , 00H 01H is the data address , 00H 02H is data length , 20H 0BH is check code.
   Slave reply: 01H 04H 04H 00H 00H 01H 00H FAH 14H
   Note: 01 is encoder address, 04H is the function code, 04H is the data length, 00H 00H 01H 00H is the data, FAH 14H is check code.
   For encoder parameter setting, please use our company’s special CALT software.

지침을 운영하십시오 : (Before opening the serial port, please configure the serial port communication mode according to the encoder parameters)

Modbus communication considerations:

1. Communication speed and transmission distance is a contradiction. The higher the rate, the transmission distance is shorter, but more stable, and vice versa.

2. External reset line (gray wire) used to reset the encoder current position to presetting value. When using, the gray wire should connected to high level (24V). But after the completion of the operation, It’s better to connect gray wire to power ground to avoid interference.

3. In the strong external electromagnetic interference, RS485 connection is best to use double-shielded cable.

4. When multiple encoders connect host, because of the encoder have no parity, it is suggested that when the PC programming in time to distinguish between the various encoder data returned.

5. When the system has a motor, encoder power supply should be isolated from other.

Since RS485 circuit is a differential form, A, B are two signal lines with voltage, often times connect to ground or high level, RS485 circuit will cause damage
