Operator Programming Error Codes, Causes, and Possible Solutions
A 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 HOA keypad 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

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)
• 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)
• 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) and PID control
(b5-01) are enabled simultaneously
Settings for N.C. and N.O. input for the following
functions were selected simultaneously:
• External Search Command 1 and External
Search Command 2 (61 vs. 62)
• Fast Stop N.O. and Fast Stop N.C. (15 vs. 17)
• FWD Run Command (or REV) and FWD/REV
Run Command (2-wire) (40, 41 vs. 42, 43)
• Drive Enable (60 vs. 6A)

Unit Capacity Setting Fault
Unit 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.
• Check if contradictory settings have simultaneously been assigned to the multi-function input
terminals.
• Correct setting errors.
