Exception

Meaning

code

 

1

Illegal command code: The command code received in the command

message is not available for the AC drive.

 

2

Illegal data address: The data address received in the command

message is not available for the AC drive.

 

3

Illegal data value: The data value received in the command message

is not available for the AC drive.

 

4

Slave device failure: The AC drive is unable to perform the requested

action.

 

The AC drive receives the messages, but detects a communication error, thus, no response is returned, but there will be error message “CExx” displayed on the keypad of AC drive. The master device will eventually process a timeout condition. The xx of “CExx” is a decimal code, the meaning of the error message is below:

Error

AC drive busy:

6

The time interval between commands is too short. Please keep an

interval of 10ms at least after the return of a command. If no command

 

 

returned, please keep a 10ms interval at least for the same reason.

7

9

Check Sum Error: Check if the Check Sum is correct.

10

Watchdog Timer: The timer will reset to 0 after each valid Modbus

communication message is received.

 

11

Frame Error: Check if the Baud rate complies with the data format.

12

The command message is too short.

13

Command message length is out of range.

 

The command messages include the data that does not belong to ‘0’ to

14

‘9’, ‘A’ to ‘F except starting and end character (only for Modbus ASCII

 

mode).
