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.
Er-17
Reverse Prohibited
Error
b1-04 = 1 [Reverse Operation
Selection = Reverse 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 [Reverse Enabled]
.
3.
Do Inertia Tuning again.
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 doing
Stationary Auto-Tuning, the motor
may not be able to use high
frequency injection control. Contact
Yaskawa or your nearest sales
representative for more information.

Operating Mode Display
When you use the LCD keypad to do the backup function, the keypad shows the running
operation on the LCD display. These indicators do not show that an error has occurred.
