Code Error
4023 Not enough test data to analyse
(_ecINSUFFICIENT_TEST_DATA)
4024 Flux model parameters are invalid
(_ecINVALID_FLUX_MODEL)
4025 Load model is invalid
(_ecINVALID_LOAD_MODEL)
4026 Encoder parameter invalid
4027 Motor inductance is not set
Cause
This error can occur during any
of the autotuning tests, namely
the Measure motor resistance
and inductance test, the
Measure the voltage constant
and Measure the motor inertia
tests, and the Feedback
calibration test (for absolute
encoders only). Generally, error
4023 means that insufficient
data was logged during the test
to obtain accurate parameter
measurement.
The Measure the motor inertia
test will fail with this error if the
voltage constant has not been
defined.
If this error occurs during the
Measure the motor inertia test, it
suggests that the characteristics
of the load are such that inertia
cannot be accurately calculated.
Error 4025 can also occur
during the Calculate the speed
and position gains test if the
values of load inertia and
damping have not been defined.
Either;
EncoderResolution < 1 or
EncoderCycleSize = 0.
When motor type is AM, Lm or
Llr <= 0.

What to do
See errors 4018 , 4019 and 4020 for
the reasons why these tests fail.
To determine the voltage constant,
either select a standard motor from
the database in the Drive Setup
Wizard , enter a voltage constant
value in the Confirm Motor
Information page of the Drive Setup
Wizard (see manufacturer's motor
data), or run the Measure the voltage
constant test.
See error 4020 for more information.
In this case, run the Measure the
motor inertia test to measure load
inertia and damping.
Correct Encoder parameters and re
run autotune tests
To avoid this error, make sure that a
motor has been selected from the
database in the Drive Setup Wizard.
Alternatively, if a custom motor has
been selected and you are unsure of
motor data, check that the "Measure
motor resistance and inductance"
test has been selected and run using
the Autotune tool.
