Error Code
(Hex.)
Error Name and Cause
•
During an EEPROM data error (
CPF06 [EEPROM Memory Data Error]
), the master attempted to write to a parameter other than
A1-00 [Language
Selection]
,
A1-01 [Access Level Selection]
,
A1-02 [Control Method Selection]
,
A1-03 [Initialize Parameters]
,
A1-04 [Password]
,
A1-05 [Password Setting]
,
E1-03 [V/f Pattern Selection]
, or
o2-04 [Drive Model (KVA) Selection]
.
•
Attempted to write to read-only data.

DC Bus Undervoltage Write Error
•
Attempted to write from the master during a
Uv1 [DC Bus Undervoltage]
.
•
Attempted to execute and Enter command during a
Uv1 [DC Bus Undervoltage]
.

Writing Error during Parameter Processing
Master attempted writing to the drive while the drive was processing parameter data.
25
Writing into EEPROM Disabled
Writing into EEPROM write is disabled, but EEPROM write was executed from the MEMOBUS/Modbus network. When this error occurs, the keypad shows a
message and the drive continues operation.
■
Control Connection Timeout
The option has a safety feature that declares a fault if communications between the master and drive is lost after
the master commanded the drive to run.
A controlled connection is defined as one in which a master commands the drive by writing to register 01 (Hex.).
After this write, the option will begin a timer. The timer will be reset upon subsequent writes to register 01 (Hex.).
If the timer exceeds the value programmed in drive parameter
F7-16 [Timeout Value]
, the option will declare a
bUS [Option Communication Error]
if the option has an active run command to the drive. A value of 0 in
F7-16
means that the timeout is disabled.
The drive reaction to a
bUS
is programmable through drive parameter
F6-01 [Communication Error Selection]
.

Web Interface
The option contains a series of web pages that allow for viewing of status and diagnostic information through a
standard web browser.
The web page is accessed through a self-contained web server at port 80. Access the home page by typing the IP
address of the option in a web browser. Example: "http://192.168.1.20
”
The IP address of the option can be read using monitors
U6-80 to U6-83 [Option IP Address 1 to Option IP
Address 4]
on the keypad if it is unknown.Refer to
