Error name

 

 

Description

Error code

 

 

 

Impossible to

exe-

The command is impossible to execute, though communication was

0000

cute

 

established normally.

 

 

 

1 Writing data into a parameter whose setting cannot be changed

 

 

 

during operation (e.g., maximum frequency) *1

 

 

 

2 Writing data into a parameter while “” is in progress

 

Data error

 

Invalid data is specified.

0001

Communication

 

There is no communication number that matches.

0002

number error

 

 

 

 

Command error

 

The command specified does not exist.

0003 (ASCII mode)

 

 

 

 

No code returned (Binary

 

 

 

 

mode)

Checksum error

 

The Checksum does not match.

0004

Format error

 

The data transmission format does not match.

No code returned

 

 

1 One-digit inverter number (ASCII mode)

 

 

 

2 The CR code is found in the designated position. (ASCII mode)

 

 

 

Ex.:Communication number of 4 digit or less. In the case of (R11)

 

 

 

CR, 11) CR is recognized as a communication number and

 

 

 

the CR code is not recognized, with the result that a format

 

 

 

error occurs.

 

 

 

3 A code other then the stop code (“)”) is entered in the stop code

 

 

 

position.

 

 

Receiving error

 

A parity, overrun or framing error has occurred. *2

No code returned

 

*1: For parameters whose settings cannot changed during operation, see ”Table of parameters.”

 

*2: Parity error

: The parity does not match.

 

 

 

Overrun error

: A new data item is entered while the data is being read.

Framing error : The stop bit is placed in the wrong position.

*For the errors with “no code returned” in the above table, no error code is returned to avoid a data crash.

If no response is received, the computer side recognizes that a communication error has occurred. Retry after a lapse of some time.

*If the inverter number does not match, no processing will be carried out and no data will be re- turned, though it is not regarded as an error.
