4016 Mathematic error in gain
calculations
(_ecGAIN_CALCS_FAILED)
This error can occasionally occur
during the Calculate current loop
gains or Calculate the speed
and position gains tests,
indicating a numerical problem
in the gain equations. It can also
indicate a problem with the
values of motor resistance and
inductance (MOTORRS and
MOTORLS) when it occurs
during current loop gain
calculations, or with the values of
inertia and damping
(LOADINERTIA and
LOADDAMPING) when it
occurs during speed/position
loop gain calculations.
The error can usually be cleared by
changing the design bandwidth for
the appropriate operation (click
Options... in the Autotune tool). If that
fails, try running the entire autotuning
sequence again.
4017 Drive setup is invalid
This error can potentially occur
in any of the autotuning
operations, although it is rare. It
indicates a problem with the
fundamental setup of the drive
such as the settings for motor
rated current or peak current.
Try running the Commissioning
Wizard again, making sure that the I
am starting a new application. Reset
memory to factory defaults option on
the Welcome page is selected.
4018 Can't fit model to voltage/current
data
(_ecCANNOT_FIT_RESISTANCE_
MODEL)
During the Measure motor
resistance and inductance test, a
gradually increasing voltage is
applied to the motor and the
generated current is logged. The
process is stopped when the
drive current reaches 80% of
the specified motor rated current
value. The resulting
voltage/current characteristic is
used to calculate the resistance
of the windings and certain
parameters of the drive's power
stage. Error 4018 will occur if
there is not enough data in the
voltage/current characteristic to
perform the calculation.
Check the wiring between the drive
and motor and the motor windings for
open circuits
4019 Can't fit model to voltage/current
transient
(_ecCANNOT_FIT_INDUCTANCE
_MODEL)
During the Measure motor
resistance and inductance test,
stator inductance is measured
by applying a voltage step to the
motor and logging the generated
current waveform. Inductance is
then calculated from the
resulting voltage/current
characteristic. Error 4019
indicates that this calculation
cannot be performed because
of insufficient data or an unusual
characteristic.
Try skipping the Measure motor
resistance and inductance test. To
do this, manually enter the motor
resistance and inductance in the
Confirm Motor Information page of
the Drive Setup Wizard (most motor
manufacturers will supply this
information) and confirm that the test
is not selected in the Autotune tool.
Once autotuning is complete, check
that the response of the current
controllers is satisfactory using the
Fine-tuning tool's Current tab.
