5. Exception response:
When drive is doing communication connection, if an error occurs drive will respond the error
code and set the highest bit (bit 7) of code to 1 (function code AND 80H) then response to control
system to know that an error occurred.
If keypad displays “CE-XX” as a warning message, “XX” is the error code at that time. Please
refer to the meaning of error code in communication error for reference.
Example:
ASCII mode: RTU mode:
STX ‘:’ Address 01H
Address
‘0’ Function 86H
‘1’ Exception code 02H
Function
‘8’ CRC CHK Low C3H
‘6’ CRC CHK High A1H
Exception code
‘0’
‘2’
LRC CHK
‘7’
‘7’

Delay Time of Communication Response
Factory Setting: 2.0
Settings 0.0~200.0 ms
 This parameter is the response delay time after AC motor drive receives communication
command as shown in the following.
PC or PLC command
Handling time
of the AC drive
Response Delay Time
Pr.09-09
Response Message
of the AC Drive
RS-485 BUS
Main Frequency of the Communication
Factory Setting: 600.0
Settings 0.0~1500.0 Hz
 When Pr. 00-20 is set to 1 (RS-485 communication). The AC motor drive will save the last
frequency command into Pr. 09-10 when abnormal turn-off or momentary power loss. After
reboots the power, it will regard the frequency set in Pr. 09-10 if no new frequency command is
inputted. When frequency command of 485 is changed (the source of frequency command
needs to be set as MODBUS), this parameter is also be changed.
RS-485 MODBUS
