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’
END

The explanation of exception codes:
Exception code Explanation
1 Function code is not supported or unrecognized.
2 Address is not supported or unrecognized.
3 Data is not correct or unrecognized.
4 Fail to execute this function code
Delay Time of Communication Response
Factory Setting: 2.0
Settings 0.0~200.0 ms
This parameter is the response delay time after hybrid servo 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: 60.00
Settings 0.00~599.00 Hz
When Pr.00-20 is set to 1 (RS-485 communication). The hybrid servo drive will save the last frequency
command at Pr.04-06 when abnormal turn-off or momentary power loss.
After rebooting the power, if no new frequency command is given, the hybrid servo drive will continue to run
by using the frequency set at Pr.04-06.
