Communications Parameters
Communication Address
Default Setting: 01
Range: 01 to 254
If the AC drive is controlled by serial communication, the communication address
must be set via this parameter.
Transmission Speed
Default Setting: 01
Settings:
00 4800 baud data transmission speed
01 9600 baud data transmission speed
02 19200 baud data transmission speed
03 38400 baud data transmission speed
This parameter is used to set the transmission speed between the computer and
AC drive. Users can set parameters and control the operation of the AC drive via
the RS-485 serial interface of a personal computer.
Communication Protocol
Default Setting: 00
Settings:
00 MODBUS ASCII mode <7 data bits, no parity, 2 stop bits>
01 MODBUS ASCII mode <7 data bits, even parity, 1 stop bit>
02 MODBUS ASCII mode <7 data bits, odd parity, 1 stop bit>
03 MODBUS RTU mode <8 data bits, no parity, 2 stop bits>
04 MODBUS RTU mode <8 data bits, even parity, 1 stop bit>
05 MODBUS RTU mode <8 data bits, odd parity, 1 stop bit>
Each DURA
PULSE
AC drive has a pre-assigned communication address specified by
P9.00. The master computer or PLC then controls each AC drive according to its
communication address. DURA
PULSE
drives can be set up to communicate on
Modbus networks using one of the following modes: ASCII (American Standard
Code for Information Interchange), or RTU (Remote Terminal Unit). Users can
select the desired mode along with the serial port communications protocol using
the settings above.
