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.
HOA Keypad Display
oPE01
Cause
The drive model selection (o2-04) and the actual
capacity of the drive are not the same.
HOA Keypad Display
oPE02
Cause
Parameters were set outside the possible setting
range.
Note: When multiple errors occur simultaneously, other errors are given precedence over oPE02.

oPE03
Cause
• 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
simultaneously:
• 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)
The Up/Down command (10, 11) and PID control
(b5-01) are enabled simultaneously.

Table 5.6 oPE Codes, Causes, and Possible Solutions
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.
Properly set the functions that required for use in combination with other functions.
Properly set the functions that required for use in combination with other functions.
• Check if contradictory settings have simultaneously been assigned to the multi-function input
terminals.
• Correct setting errors.
Set b5-01 to 0 to disable control PID or disable the Up/Down command.
