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.
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]
Correct the parameter settings.
Note:
You cannot use Speed Feedback (V/F Control) with the Motor
Switch function.
When A1-02 = 5 [OLV/PM], 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, 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
]
Set E5-09 or E5-24 to the correct value.
When A1-02 = 5, 6, you set E5-09 ≠ 0 and E5-24 ≠
0.
Set E5-09 = 0 or 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.
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 [Enabled (Standard), Enabled (D =
Feedforward)]
• 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 [Enabled (Standard), Enabled (D =
Feedforward)]
• b5-11 = 1 [PID Output Reverse Selection =
Negative Output Accepted]
Correct the parameter settings.
These parameters are set at the same time:
• b5-01 = 3, 4 [Trim (Fref+PID Out, D = Fdbk),
Trim (Fref+PID Out, D = FeedFwd)]
• d2 -02≠ 0.0 has been set.
Correct the parameter settings.
Note:
The drive detects this error if the PID control function selection is incorrect.
(When b5-01 = 1 to 4 [PID Mode Setting = PID Control Enabled])
