5.5 Operator Programming Errors
5.5 Operator Programming Errors
◆
Operator Programming Error Codes, Causes, and Possible Solutions
An Operator Programming Error (oPE) occurs when a contradictory parameter is set or an individual parameter is set to
an inappropriate value.
The regenerative unit will not operate until the parameter or parameters causing the problem are set correctly. An oPE,
however, does not trigger an alarm or fault output. If an oPE occurs, investigate the cause and refer to
for the
appropriate action. When an oPE appears on the operator display, press the ENTER button to view U1-18 and see which
parameter is causing the oPE.

Err
EEPROM Write Error A verification mismatch occurred when writing data to the EEPROM.
Cause
Possible Solutions
The data was corrupted by noise when writing
data to the EEPROM.
• Press .
• Set the parameters again.
• Cycle the power supply. Refer to
Diagnosing and Resetting Faults on page 103
for details.
EEPROM Hardware Failure
Replace the board or regenerative unit. For information on board replacement, consult with your
Yaskawa representative or the nearest Yaskawa sales office.

oPE01
Unit Capacity Setting
Error
Unit capacity and the value set to o2-04 do not match.
Cause
Possible Solutions
The Unit Model Selection (o2-04) and the
actual capacity of the regenerative unit are not
the same.
Correct the value set to o2-04.

oPE02
Parameter Range
Setting Error
Use U1-18 to find parameters set outside the range.
Cause
Possible Solutions
Parameters were set outside the possible setting
range.
Set parameters to the proper values.
Note:
When multiple errors occur simultaneously, other errors are given precedence over oPE02.

Multi-Function Input
Selection Error
A contradictory setting is assigned to multi-function contact inputs H1-01 to H1-08.
Cause
Possible Solutions
The same function is assigned to two
multi-function inputs. Excludes “Not used” and
“External Fault.”
• Ensure all multi-function inputs are assigned to different functions.
• Re-enter the multi-function settings to ensure this does not occur.

Terminal Board
Mismatch Error
The regenerative unit or the removable terminal block with parameter backup was replaced.
Cause
Possible Solutions
The regenerative unit was replaced (but the
removable terminal block with parameter
backup was not replaced).
Set A1-03 to 5550 to load the parameter settings stored in the terminal board to the regenerative
unit. Initialize parameters after regenerative unit replacement by setting A1-03 to 2220.
The removable terminal block with parameter
backup was replaced.
