Code Name Causes Possible Solutions
These parameters are set at the
same time:
• b1-01 = 4 [Pulse Train Input]
• H6-01 ≠ 0 [Terminal RP Pulse
Train Function ≠ Frequency
Reference]
Set H6-01 = 0.
oPE07
Analog Input Selection
Error
The settings for H3-02 and H3-10
[MFAI Function Select] and H7-30
[Virtual Analog Input Selection]
overlap.
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]
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
Remove the function settings that are not in
use.
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.
