Group 3: P3-xx Communication Parameters
P3 - 00
ADR
Communication Address
Communication Addr.: 0300H
Default: 1
Applicable Control Mode: P/S/T
Range: 0~254
If the AC servo drive is controlled by RS-232/485/422 communication, each drive (or device)
must be uniquely identified and addressed between 1 and 254. Access to program this number is
via parameter P3-00.
One servo drive only can set one communication address. If the communication address is
duplicate, there will be a communication fault. If the communication address is set to 0, it is with
broadcast function.
P3 - 01
BRT
Transmission Speed
Communication Addr.: 0301H
Default: 1
Applicable Control Mode: P/S/T
Range: 0~5
Unit: bps
Setting:
0: Baud rate 4800 (data transmission speed: bits / second)
1: Baud rate 9600 (data transmission speed: bits / second)
2: Baud rate 19200 (data transmission speed: bits / second)
3: Baud rate 38400 (data transmission speed: bits / second)
4: Baud rate 57600 (data transmission speed: bits / second)
5: Baud rate 115200 (data transmission speed: bits / second)
This parameter is used to set the desired transmission speed between the computer and AC
servo drive. Users can set this parameter and control transmission speed to reach the maximum
baud rate of 115200 bps.
P3 - 02
PTL
Communication Protocol
Communication Addr.: 0302H
Default: 0

Setting:
0: Modbus ASCII mode, <7,N,2>
1: Modbus ASCII mode, <7,E,1 >
2: Modbus ASCII mode, <7,O,1>
3: Modbus ASCII mode, <8,N,2 >
4: Modbus ASCII mode, <8,E,1>
5: Modbus ASCII mode, <8,O,1>
6: Modbus RTU mode, <8,N,2>
7: Modbus RTU mode, <8,E,1>
8: Modbus RTU mode, <8,O,1>
