Each VFD-EL AC motor drive has a pre-assigned communication address specified by Pr.09.00. The RS485
master then controls each AC motor drive according to its communication address.
09.00
Communication Address
Settings 1 to 254 Factory Setting: 1
 If the AC motor drive is controlled by RS-485 serial communication, the communication address for this
drive must be set via this parameter. And the communication address for each AC motor drive must be
different and unique.
09.01
Transmission Speed
Factory Setting: 1
Settings 0 Baud rate 4800 bps (bits / second)
1 Baud rate 9600 bps
2 Baud rate 19200 bps
3 Baud rate 38400 bps
 This parameter is used to set the transmission speed between the RS485 master (PC, etc.) and AC motor
drive.
09.02
Transmission Fault Treatment
Factory Setting: 3
Settings 0 Warn and keep operating
1 Warn and RAMP to stop
2 Warn and COAST to stop
3 No warning and keep operating
 This parameter is set to how to react if transmission errors occur.
 See list of error messages below (see section 3.6.)
09.03
Time-out Detection
Unit: 0.1
Settings 0.0 to 120.0 sec Factory Setting: 0.0
0.0 Disable
 If Pr.09.03 is not equal to 0.0, Pr.09.02=0~2, and there is no communication on the bus during the Time Out
detection period (set by Pr.09.03), “cE10” will be shown on the keypad.
09.04
Communication Protocol
Factory Setting: 0
Settings 0 Modbus ASCII mode, protocol <7,N,2>
1 Modbus ASCII mode, protocol <7,E,1>
2 Modbus ASCII mode, protocol <7,O,1>
3 Modbus RTU mode, protocol <8,N,2>
4 Modbus RTU mode, protocol <8,E,1>
5 Modbus RTU mode, protocol <8,O,1>
6 Modbus RTU mode, protocol <8,N,1>
7 Modbus RTU mode, protocol <8,E,2>
8 Modbus RTU mode, protocol <8,O,2>
9 Modbus ASCII mode, protocol <7,N,1>
10 Modbus ASCII mode, protocol <7,E,2>
11 Modbus ASCII mode, protocol <7,O,2>
