7.6 Parameter Setting Errors
Parameter setting errors occur when multiple parameter settings do not agree, or when parameter setting values
are not correct. Refer to the table in this section, examine the parameter setting that caused the error, and remove
the cause of the error. You must first correct the parameter setting errors before you can operate the drive. The
drive will not send notification signals for the faults and alarms when these parameter setting errors occur.
Code Name Causes Possible Solutions
oPE01 Drive Capacity Setting Error
The value set in o2-04 [Drive Model (KVA)
Selection] does not agree with the drive model.
Set o2-04 to the correct value.
Code Name Causes Possible Solutions
oPE02 Parameter Range Setting Error Parameter settings are not in the applicable setting
range.
1. Push to show U1-18 [oPE Fault Parameter] , and find
parameters that are not in the applicable setting range.
2. Correct the parameter settings.
Note:
• If more than one error occurs at the same time, other oPExx
errors have priority over oPE02 .
Set E2-01 ≤ E2-03 [Motor Rated Current (FLA) ≤
Motor No-Load Current] .
Make sure that E2-01 > E2-03 .
Note:
If it is necessary to set E2-01 < E2-03 , first lower the value
set in E2-03 , and then set E2-01 .
Code Name Causes Possible Solutions
oPE03 Multi-Function Input Setting Err
The settings for these parameters do not agree:
• H1-01 to H1-07 [Terminals S1 to S7 Function
Selection]
Correct the parameter settings.
The settings for MFDIs overlap.
Note:
This does not include H1-xx = 20 to 2F [MFDI
Function Select = External Fault] and
[Reserved] .
Set the parameters correctly to prevent MFDI function overlap.
You did not set these pairs of MFDI functions to
Digital Inputs (
H1-xx ) at the same time.
Set the MFDI pairs.
You set a minimum of two of these MFDI
combinations to Digital Inputs (
H1-xx ) at the same
time.
Remove the function settings that are not in use.
Settings for N.C. and N.O. input [H1-xx] for these
functions were selected at the same time:
• Setting value 15 [Fast Stop (N.O.)]
• Setting value 17 [Fast Stop (N.C.)]
Remove one of the function settings.
These parameters are set at the same time:
• H1-xx ≠ 6A [Drive Enable]
• H2-xx = 38 [Drive Enabled]
Correct the parameter settings.
• Multistep frequency reference [D1-18 = 0] and
H1-xx = 50/150, 51/151, 52/152 or 53/153 are
selected.
• Speed reference by digital input [D1-18 = 1] and
multi-step speed references 3/103, 4/104 or 5/
105 are selected.
Check if contradictory settings have been assigned to the multi-
function terminals at the same time. Correct setting errors.

oPE08 Parameter Selection Error
A function was set that is not compatible with the
control method selected in
A1-02 [Control Method
Selection] .
1. Push ENTER Key to show U1-18 [oPE Fault Parameter] ,
and find parameters that are not in the applicable setting
range.
2. Correct the parameter settings.
Note:
If more than one error occurs at the same time, other oPExx
errors have priority over oPE02 .
When A1-02 = 2 [OLV] , you used these parameter
settings:
•
n2-02 > n2-03 [Automatic Freq Regulator Time
1 > Automatic Freq Regulator Time 2]
• C4-02 > C4-06 [Torque Compensation Delay
Time > Motor 2 Torque Comp Delay Time]
• Set n2-02 < n2-03 .
• Set C4-02 < C4-06 .
