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 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
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
The drive model selection (o2-04) and the actual capacity of the drive are
not the same.

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-oo = 42), but
Forward/Reverse command (H1-oo = 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).

Cause
Drive Capacity Setting Fault
Drive capacity and the value set to o2-04 do not match.
Correct the value set to o2-04.
Parameter Range Setting Error
Use U1-18 to find parameters set outside the range.
Set parameters to the proper values.
Multi-Function Input Selection Error
A contradictory setting is assigned to multi-function contact inputs H1-01
to H1-08.
• 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.
