2.6 Parameter Setting Errors
Code Name
oPE07 Analog Input Selection Error
Code Name
oPE08 Parameter Selection Error
72
Causes
The settings for H3-02 and H3-10 [MFAI Function
Select] and H7-30 [Virtual Analog Input Selection]
overlap.
These parameters are set at the same time:
• H3-02, H3-10, H7-30 = B [PID Feedback]
• H6-01 = 1 [Terminal RP Pulse Train Function =
PID Feedback Value]
These parameters are set at the same time:
• H3-02, H3-10, H7-30 = C [PID Setpoint]
• H6-01 = 2 [PID Setpoint Value]
These parameters are set at the same time:
• H3-02, H3-10, H7-30 = C
• b5-18 = 1 [PID Setpoint Selection = Enabled]
These parameters are set at the same time:
• H6-01 = 2
• b5-18 = 1
Causes
A function was set that is not compatible with the
control method selected in A1-02 [Control Method
Selection].
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]
When A1-02 = 0 [V/f], you used these parameter
settings:
• H6-01 = 3 [Terminal RP Pulse Train Function =
Speed Feedback (V/F Control)]
• H1-xx = 16 [MFDI Function Select = Motor 2
Selection]
When A1-02 = 5 [OLV/PM], you set E5-02 to E5-07
[PM Motor Parameters] = 0.
When A1-02 = 5, 6 [OLV/PM, AOLV/PM], you used
these parameter settings:
• E5-09 = 0.0 [PM Back-EMF Vpeak (mV/(rad/s))
= 0.0 mV/(rad/s)]
• E5-24 = 0.0 [PM Back-EMF L-L Vrms (mV/rpm)
= 0.0 mV/min -1 ]
When A1-02 = 5, 6, you set E5-09 ≠ 0 and E5-24 ≠ 0.
When A1-02 = 6, you set these parameters:
• n8-57 = 0 [HFI Overlap Selection = Disabled]
• You set E1-09 [Minimum Output Frequency] < the
5% value of E1-06.
When A1-02 = 6, you set these parameters:
• n8-35 = 0 [Initial Pole Detection Method = Pull-
in]
• n8-57 = 1 [Enabled]
When A1-02 = 8 [EZOLV], you used these parameter
settings:
• E9-01 = 1, 2 [Motor Type Selection = Permanent
Magnet (PM), Synchronous Reluctance (SynRM)]
• b3-24 = 2 [Speed Search Method Selection =
Current Detection 2]

Possible Solutions
Set H3-02, H3-10, and H7-30 correctly to prevent overlap.
Note:
It is possible to set these functions to multiple analog input
terminals at the same time:
• Setting value 0 [Frequency Reference]
• Setting values F and 1F [Not Used]
Remove the function settings that are not in use.
Possible Solutions
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.
• Set n2-02 < n2-03.
• Set C4-02 < C4-06.
Correct the parameter settings.
Note:
You cannot use Speed Feedback (V/F Control) with the Motor
Switch function.
• Set E5-01 [PM Motor Code Selection] correctly as specified by
the motor.
• For specialized motors, refer to the motor test report and set E5-
xx correctly.
Set E5-09 or E5-24 to the correct value.
Set E5-09 = 0 or E5-24 = 0.
Correct the parameter settings.
Correct the parameter settings.
When E9-01 = 1 or 2, set b3-24 = 1 [Speed Estimation].
