6.6 Parameter Setting Errors
YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual 377
Code Name Causes Possible Solutions
oPE06 Control Method Selection
Error
A1-02 = 1, 3, or 7 [Control Method
Selection = CL-V/f, CLV, CLV/PM] is
set, but there is no encoder option card
connected to the drive.
• Connect an encoder option card to the drive.
• Set A1-02 correctly.
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]
The following parameters are set at the
same time:
• H3-02, H3-06, H3-10, H7-30 = B
[PID Feedback]
• H6-01 = 1 [Terminal RP Pulse Train
Function = PID Feedback Value]
The following parameters are set at the
same time:
• H3-02, H3-06, H3-10, H7-30 = C
[PID Setpoint]
• H6-01 = 2 [PID Setpoint Value]
The following parameters are set at the
same time:
• H3-02, H3-06, H3-10, H7-30 = C
• b5-18 = 1 [b5-19 PID Setpoint
Selection = Enabled]
The following parameters are set at the
same time:
• H6-01 = 2
• b5-18 = 1
Remove the function settings that are not in use.
Code Name Causes Possible Solutions
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 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.
These parameters were set in OLV
Control:
• 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.
In OLV/PM control, 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.
In PM motor control methods:
• 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.
