„ Communication Related Error Code
If one communication error occurs during communication, the AC servo drive will respond the corresponding
error value and command code plus 80H back to the external controller.
For example,
ASCII Mode RTU Mode
STX ‘:’ ADR 01H
‘0’ CMD 86H
ADR
‘1’ Error Code 02H
‘8’ CRC Check Low C3H
CMD
‘6’ CRC Check High A1H
‘0’
Error Code
‘2’
‘7’
LRC Check
‘7’
End 1 CR
End 0 LF
Error Code
Error Code Error Code Description
0x01 GRP_ERR Group Error: Read/Write unexisted parameter group
0x02 IDX_ERR Parameter Error: Read/Write unexisted parameter
0x03 VAL_ERR
Value Error: Setting value is not within the setting range.
(Higher than the maximum setting value or lower than the
minimum setting value)
0x04 OV_PT
Numbers of Data Error: Numbers of read and write data
exceed the maximum. (9 numbers)
0x05 ZO_PT 0 Number Error: Number of read and write data is 0.
0x06 WRITE_ERR Write Error: Write the read-only and reserved parameters.
0x27 OUT_OF_RANGE
Illegal Value: Although the setting value is within the setting
range, it is not a legal value for this parameter.
0x28 PASSWORD_FAIL
Password error: For security, password is needed for
reading and writing some parameters. For example, before
enabling P4-10, users have to set P2-08 to 20 first.
0x29 SRVON_WR_DISABLE
