254
Causes
The inertia found by the drive was too small or too
large during Inertia Tuning (10% or less, or
50000% or more).
Causes
b1-04 = 1 [Reverse Operation Selection =
Disabled]
Note:
You cannot do Inertia Tuning if the drive cannot
rotate the motor in reverse.
Causes
The result of the induced voltage tuning was not in
the applicable range.
Causes
The Auto-Tuning results of the PM motor
inductance were not in the applicable range.
Causes
The Auto-Tuning results of the PM Motor Stator
Resistance were not in the applicable range.
Causes
The motor data is incorrect.
Possible Solutions
• 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.
Possible Solutions
1. Enable reverse in the target machine.
2. Set b1-04 = 0 [Enabled].
3. Do Inertia Tuning again.
Possible Solutions
1. Make sure that the input motor nameplate data is correct.
2. Do Auto-Tuning again and correctly set the motor nameplate
data.
Possible Solutions
1. Make sure that the input motor nameplate data is correct.
2. Do Auto-Tuning again and correctly set the motor nameplate
data.
Possible Solutions
1. Make sure that the input motor nameplate data is correct.
2. Do Auto-Tuning again and correctly set the motor nameplate
data.
Possible Solutions
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.
