6.6 Programming Errors
u 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 Table 6.10 for the appropriate action. When
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 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.

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 by checking the modified constants menu and verifying that
settings are within the limits.
• Set Z1-01 to 1 to re-initialize the drive and bypass.
Set parameters to the proper values by checking the modified constants menu and verifying that
settings are within the limits.
Note: When multiple errors occur simultaneously, other errors are given precedence over oPE02

oPE03
Multi-Function Input Selection Error
A contradictory setting is assigned to multi-function contact inputs Z2-01 to Z2-08.
Cause Possible Solutions
• The same function is assigned to two
multi-function inputs
• Excludes “Not used” and “External Fault”
• Ensure all multi-function inputs are assigned to different functions.
• Re-enter the multi-function settings to ensure this does not occur.
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)
• KEB for Momentary Power Loss and High Slip
Braking
(65, 66, 7A, 7B vs. 68)
• KEB Command 1 and KEB Command 2 (65, 66
vs. 7A, 7B)
• FWD Run Command (or REV) and FWD/REV
Run Command (2-wire) (40, 41 vs. 42, 43)
• Drive Enable (60 vs. 6A)
• Check if contradictory settings have simultaneously been assigned to the multi-function input
terminals.
• Correct setting errors.
