Code Name Causes Possible Solutions
oPE07 Analog Input Selection Error
The settings for H3-02, H3-06, and H3-10 [MFAI
Function Select] and H7-30 [Virtual Analog Input
Selection] overlap.
Set H3-02, H3-06, 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]
oPE08 Parameter Selection Error
You set a function that is not compatible with the
control method set in A1-02 [Control Method
Selection].
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.
When A1-02 = 2 [Control Method Selection = 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.
When A1-02 = 0 [Control Method Selection = 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]
Correct the parameter settings.
Note:
You cannot use Speed Feedback (V/F Control) with the Motor
Switch function.
When A1-02 = 5 [PM Open Loop Vector], you set
E5-02 to E5-07 [PM Motor Parameters] = 0.
• 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.
When A1-02 = 5 to 7 [Control Methods for PM
Motors], 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
]
Set E5-09 or E5-24 to the correct value.
When A1-02 = 5 to 7, you set E5-09 ≠ 0 and E5-24 ≠
0.
Set E5-09 = 0 or E5-24 = 0.
When A1-02 = 6 [PM Advanced Open Loop Vector],
you used these parameter settings:
• n8-57 = 0 [HFI Overlap Selection = Disabled]
• You set E1-09 [Minimum Output Frequency] < the
5% value of E1-06.
Correct the parameter settings.
When A1-02 = 6, you set these parameters:
• n8-35 = 0 [Initial Pole Detection Method = Pull-
in]
• n8-57 = 1 [Enabled]
Correct the parameter settings.
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]
When E9-01 = 1 or 2, set b3-24 = 1 [Speed Estimation].
oPE09 PID Control Selection Fault
These parameters are set at the same time:
• b5-15 ≠ 0.0 [PID Sleep Function Start Level ≠ 0.0
Hz]
• b1-03 = 2, 3 [Stopping Method Selection = DC
Injection Braking to Stop, Coast to Stop with
Timer]
• Set b5-15 ≠ 0.0.
• Set b1-03 = 0, 1 [Ramp to Stop, Coast to Stop].
These parameters are set at the same time:
• b5-01 = 1, 2 [Standard, Standard (D on
feedback)]
• d2-02 ≠ 0.0 [Frequency Reference Lower Limit ≠
0.0%]
Correct the parameter settings.
These parameters are set at the same time:
• b5-01 = 1, 2 [Standard, Standard (D on
feedback)]
• b5-11 = 1 [PID Output Reverse Selection =
Negative Output Accepted]
Correct the parameter settings.
