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
Solutions on page 331 for the appropriate action. When an oPE appears on the operator display, press the ENTER button
to view U1-18 and see the parameter that is causing the oPE error (U1-18).

The drive model selection (o2-04) and the actual capacity of the drive are not the same.
Digital Operator Display
Parameters were set outside the possible setting range.
Note: When multiple errors occur at the same time, other errors are given precedence over oPE02.

• The same function is assigned to two multi-function inputs.
• Excludes "Not used" and "External Fault."
The Up command was set but the Down command was not, or vice versa (settings 10 vs. 11).
The Up 2 command was set but the Down 2 command was not, or vice versa (settings 75 vs.
76).
• Run/Stop command for a 2-wire sequence was set (H1- = 42), but Forward/Reverse
command (H1- = 43) was not.
• "Drive Enable" is set to multi-function input S1 or S2 (H1-01 = 6A or H1-02 = 6A).
• Two of the following functions are set at the same time:
• Up/Down Command (10 vs. 11)
• Up 2/Down 2 Command (75 vs. 76)
• Hold Accel/Decel Stop (A)
• Analog Frequency Reference Sample/Hold (1E)
• Offset Frequency 1, 2, 3 Calculations (44, 45, 46)
The Up/Down command (10, 11) is enabled at the same time as PID control (b5-01).
Settings for N.C. and N.O. input for the following functions were selected at the same time:
• External Search Command 1 and External Search Command 2 (61 vs. 62)
• Fast Stop N.O. and Fast Stop N.C. (15 vs. 17)
• Motor Switch Command and Accel/Decel Time 2 (16 vs. 1A)
• FWD Run Command (or REV) and FWD/REV Run Command (2-wire) (40, 41 vs. 42, 43)
• External DB Command and Drive Enable (60 vs. 6A)
• Motor Switch Command and Up 2/Down 2 Command (16 vs. 75, 76)
One of the following settings was entered while H1- = 2 (External Reference 1/2):
• b1-15 = 4 (Pulse Train Input) but the pulse train input selection is not set for the frequency
reference (H6-01 > 0)
• b1-15 or b1-16 set to 3 but no option card is connected
• Although b1-15 = 1 (Analog Input) and H3-02 or H3-10 are set to 0 (Frequency Bias)
H2- = 38 (Drive Enabled) but H1- is not set to 6A (Drive Enable).
H1- = 7E (Direction Detection) although H6-01 is not set to 3 (for V/f Control with PG
using terminal RP as speed feedback input).
H1- = 16 is selected when using PG-RT3.

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.

refer to oPE Codes, Causes, and Possible
Error Name
Unit Capacity Setting Fault
Unit capacity and the value set to o2-04 do not match.
Possible Solutions
Correct the value set to o2-04.
Error Name
Parameter Range Setting Error
Use U1-18 to find parameters set outside the range.
Possible Solutions
Set parameters to the proper values.
Error Name
Multi-Function Input Selection Error
A contradictory setting is assigned to multi-function contact inputs H1-01 to H1-08.
Possible Solutions
• Ensure all multi-function inputs are assigned to different functions.
• Re-enter the multi-function settings to ensure this does not occur.
Correctly set functions that need to be enabled in combination with other functions.
Correctly set functions that need to be enabled in combination with other functions.
• Check if contradictory settings have been assigned to the multi-function input terminals at
the same time.
• Correct setting errors.
Disable control PID (b5-01 = 0) or disable the Up/Down command.
Check for contradictory settings assigned to the multi-function input terminals at the same
time. Correct setting errors.
Correct the settings for the multi-function input terminal parameters.
Correct the setting. PG-RT3 is not available for the application with Motor 2 Selection.
Error Name
Terminal Board Mismatch Error
Possible Solutions
Set A1-03 to 5550 to load the parameter settings stored in the terminal board to the drive.
Initialize parameters after drive replacement by setting A1-03 to 2220 or 3330.
