Causes
Possible Solutions
Er-18
Back EMF Error
The result of the induced voltage tuning was not in
the applicable range.
1.
Make sure that the input motor nameplate data is correct.
2.
Do Auto-Tuning again and correctly set the motor nameplate
data.
Er-19
PM Inductance Error
The Auto-Tuning results of the PM motor inductance
were not in the applicable range.
1.
Make sure that the input motor nameplate data is correct.
2.
Do Auto-Tuning again and correctly set the motor nameplate
data.
Er-20
Stator Resistance Error
The Auto-Tuning results of the PM Motor Stator
Resistance were not in the applicable range.
1.
Make sure that the input motor nameplate data is correct.
2.
Do Auto-Tuning again and correctly set the motor nameplate
data.
Er-25
HighFreq Inject Param Tuning Err
The motor data is incorrect.
Do Stationary Auto-Tuning again.
Note:
If the drive detects
Er-25
after you do Stationary Auto-Tuning,
it is possible that the motor cannot use high frequency injection.
For more information, contact Yaskawa or your nearest sales
representative.

Possible Solutions
CPEr
Control Mode Mismatch
The keypad setting and drive setting for
A1-02
[Control Method Selection]
do not agree.
1.
Set
A1-02
on the drive to the same value that is on the keypad.
2.
Restore the parameters.
CPyE
Error Writing Data
Parameter restore did not end correctly.
Restore the parameters.
CSEr
Control Mode Mismatch
The keypad is broken.
Replace the keypad.
dFPS
Drive Model Mismatch
You tried to restore parameters to a different drive
model than the one that you backed up.
1.
Examine the drive model that you used to back up the
parameters.
2.
Restore the parameters.
iFEr
Keypad Communication Error
There was a communications error between the
keypad and the drive.
Examine the connector or cable connection.
ndAT
Error Received Data
The parameter settings for model and specifications
(power supply voltage and capacity) are different
between the keypad and the drive.
1.
Make sure that drive model and the value set in
o2-04 [Drive
Model (KVA) Selection]
agree.
2.
Restore the parameters.
The parameters are not stored in the keypad.
1.
Connect a keypad that has the correct parameters.
