Modbus Communications Error Code List
This table lists the Modbus communications error codes.
When an error occurs, remove the cause of the error and restart communications.
Table 6.15 Modbus Communications Error Codes
Error Code
(Hex.)
Name
Cause
01
Function Code Error
The PLC set a function code that was not 03, 08, or 10 (Hex.)
02
Register Number Error
•
The register number that is trying to access is not registered.
•
A starting number that was not 0001 or 0002 (Hex.) was set when broadcasting.
03
Bit Count Error
•
Read and write data quantities are more than the 1 to 16 range. (Command message data quantity is disabled.)
•
The data that was read from non-consecutive holding registers contained more than 120 bytes.
•
The data to be written to non-consecutive holding registers contained more than 60 bytes.
•
In the write mode, the number of bytes in the message is not the number of data × 2.
21
Data Setting Error
•
Writing control data or parameters made the settings go out of the permitted setting range.
•
A parameter setting error occurred when writing a parameter.
22
Write Mode Error
•
Tried to write a disabled parameter during run.
•
When there was a
CPF06 [Control Circuit Error]
, the master tried to write a parameter other than one of these:
–
A1-00 [Language Selection]
–
A1-01 [Access Level]
–
A1-02 [Control Method]
–
A1-03 [Init Parameters]
–
A1-04 [Password Input]
–
A1-05 [Password Setting]
–
E1-03 [V/f Pattern Selection]
–
o2-04 [Drive KVA Selection]
•
Writes the read-only data.
23
DC Bus Undervoltage
Write Error
During
Uv [DC Bus Undervoltage]
, a
Uv
write disabled parameter was written.
24
Error Writing Data During
Parameter Processing
Tried to write a parameter from the master during parameter processing on the drive side.
25
Writing into EEPROM
Disabled
Writing into EEPROM write is disabled, but EEPROM write was executed from Modbus communications. When this error
occurs, the keypad shows a message and the drive continues operation.
