Technical Manual for EA350 Analog Pulse Type Servo Driver V101 8.12 P7-xx communication parameters Parameter functions: This device is used as the address of the communication slave station. Parameter functions: Set the baud rate for communication of the device P7-01=0 : 4800 bps P7-01=1 : 9600 bps P7-02=2 : 19200 bps P7-03=3 : 38400 bps P7-04=4 : 57600 bps P7-04=5 : 115200 bps Parameter functions: Set the communication data format for the device P7-02=0 : No check 1+8+N+1 (1 start bit + 8 data bits + no check bit + 1 stop bit) P7-02=1 : Odd parity check 1+8+O+1 (1 start bit + 8 data bits + odd parity bit + 1 stop bit) P7-02=2 :
Odd parity check 1+8+E+1 (1 start bit + 8 data bits + even parity bit + 1 stop bit) P7-02=3 : No check 1+8+N+2 (1 start bit + 8 data bits + no check bit + 2 stop bits) P7-02=4 : Odd parity check 1+8+O+2 (1 start bit + 8 data bits + odd parity bit + 2 stop bits) P7-02=5 : Odd parity check 1+8+E+2 (1 start bit + 8 data bits + even parity bit + 2 stop bits) Parameter functions: Set the delay time of communication response When the device receives a communication command from the upper computer, response will be delayed for the length of the time. Parameter functions: Bit0=0 : Whether data sent to the driver via MODBUS communication will be saved depends on the setting of P7-05. Bit0=1 :
Data sent to the driver via MODBUS communication will never be saved. Bit1=0 : Received data is returned upon receipt of a write command via MODBUS communication, and write is executed. Bit1=1 : Received data is not returned upon receipt of a write command via MODBUS communication, and write is executed.
