6.5 Operator Programming Errors
◆ oPE 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 drive 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 Table 6.10 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.

Digital Operator Display Error Name
oPE01
Drive Capacity Setting Fault
Drive capacity and the value set to o2-04 do not match.
Cause Possible Solutions
The drive model selection (o2-04) and the actual capacity of the drive are not the same. Correct the value set to o2-04.
Digital Operator Display Error Name
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 at the same time, other errors are given precedence over oPE02.
Digital Operator Display Error Name
oPE03
Multi-function Digital Input Selection Error
A contradictory setting is assigned to multi-function contact inputs H1-03 to H1-08.
Cause Possible Solutions
• The same function is assigned to two multi-function inputs.
• Excludes “Brake feedback” and “Brake feedback 2.”
• Ensure all multi-function inputs are assigned to different functions.
• Re-enter the multi-function settings to ensure this does not occur.
The Brake Feedback (H1- = 79) or Brake Feedback 2 (H1- = 5B) function is assigned
to three or more multi-function inputs.
Motor contactor feedback and Motor contactor feedback 2 (56 vs. 5A) are selected
simultaneously.
Check for contradictory settings assigned to the multi-function input terminals
simultaneously. Correct setting errors.

oPE04 Terminal Board Mismatch Error
Cause Possible Solutions
The drive, control board, or terminal board has been replaced and the parameter settings
between the control board and the terminal board no longer match.
To load the parameter settings to the drive that are stored in the terminal board, set A1-03 to
5550. Initialize parameters after drive replacement by setting A1-03 to 1110 or 2220.
Digital Operator Display Error Name
oPE05 Reference Source Selection Error
Cause Possible Solutions
Speed reference is assigned to an option card (b1-01 = 3) but an input option card is not
connected to the drive.
Reconnect the input option card to the drive.
The Up/Down command is assigned to an option card (b1-02 = 3) but an input option card is
not connected to the drive.
Although the digital card input is set for BCD special for a 5 digit input (F3-01 = 6), the data
length is set for 8 bit or 12 bit (F3-03 = 0, 1).
Set the input data for 16 bit (F3-03 = 2).
Digital Operator Display Error Name
oPE06
Control Mode Selection Error
Correct the setting for the control method.
Cause Possible Solutions
A control mode has been selected that requires a PG option card to be installed, but no option
card is installed (A1-02 = 3 or 7).
• Connect a PG option card.
• Correct the value set to A1-02.
Digital Operator Display Error Name
oPE07
Multi-function Analog Input Selection Error
A contradictory setting is assigned to multi-function analog inputs H3-02 and H3-10.
Cause Possible Solutions
At least two analog input terminals are set to the same function (i.e., parameters H3-02 and
H3-10 have the same setting).
Change the settings to H3-02 and H3-10 so that functions no longer conflict.
Note: Both 0 (speed reference bias) and F (not used) can be set to H3-02 and H3-10 at the
same time.
