7.7 Auto-Tuning Errors
254 SIEPCYEUOQ2V01A Q2V Technical Manual
Code Name Causes Possible Solutions
Er-16 Inertia ID Error
The inertia found by the drive was too small or too
large during Inertia Tuning (10% or less, or
50000% or more).
• Decrease the values set for the frequency and amplitude of the
test signals used when doing inertia tuning. First, decrease the
test signal amplitude, and then do Inertia Tuning. If the error
continues, decrease the test signal frequency and do Inertia
Tuning again
• Correctly set the motor inertia as specified by the motor, and
do Inertia Tuning again.
Code Name Causes Possible Solutions
Er-17 Reverse Prohibited Error
b1-04 = 1 [Reverse Operation Selection =
Disabled]
Note:
You cannot do Inertia Tuning if the drive cannot
rotate the motor in reverse.
1. Enable reverse in the target machine.
2. Set b1-04 = 0 [Enabled].
3. Do Inertia Tuning again.
Code Name 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.
Code Name Causes Possible Solutions
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.
Code Name Causes Possible Solutions
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.
Code Name Causes Possible Solutions
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 doing Stationary Auto-Tuning,
the motor may not be able to use high frequency injection
control. Contact the manufacturer or your nearest sales
representative for more information.
