Code Error Cause What to do
4028 Can't set stator resistance
(_ecCANNOT_SET_STATOR_RE
SISTANCE)
Can't set stator resistance. Error codes 4028 to 4054 will occur if
the associated drive parameter,
calculated by one of the autotuning
tests, or set by the user is outside the
allowable range of values. These
errors should not normally occur.
If the problems persist, 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. If the
problem persists you will need to
manually tune the control loops in the
drive.
4029 Can't set stator leakage inductance
(_ecCANNOT_SET_STATOR_IND
UCTANCE)
Can't set stator leakage
inductance.
4030 Motor pole pitch invalid Calculated motor pole pitch <= 0.
4031 Motor pole number invalid Calcualted motor poles < 2.
4032 Load inertia is not set Calcaulted load inertia <= 0.
4033 Can't set maximum motor flux
(_ecCANNOT_SET_MOTOR_MAX
_FLUX)
Can't set motor flux model time

Can't set load damping.
4037 Can't set controller proportional
gain
(_ecCANNOT_SET_GAIN_KIPRO
P)
Can't set controller proportional
gain.
4038 Can't set current controller integral
gain
(_ecCANNOT_SET_GAIN_KIINT)

(_ecCANNOT_SET_GAIN_KINT)
Can't set position integral gain.
4044 Can't set velocity feedforward gain
(_ecCANNOT_SET_GAIN_KVELF
F)
Can't set velocity feedforward
gain.
4045 Can't set velocity feedback gain
(_ecCANNOT_SET_GAIN_KVEL)
Can't set velocity feedback gain.
4046 Can't set acceleration feedforward
gain
(_ecCANNOT_SET_GAIN_KACCE
