Code Error
4010 Resistance too low, possible short
circuit
(_ecPOSSIBLE_SHORT_CIRCUIT
)
4011 Autotuning doesn't support
feedback device
(_ecUNSUPPORTED_FEEDBACK
_TYPE)
4012 Encoder resolver rotation sense is
wrong
(_ecFEEDBACK_SENSE_WRONG
)
Cause
This error can occur during the
Measure motor resistance and
inductance test and indicates
that the effective motor winding
resistance is very low.
The Test the feedback or
Feedback calibration test (EnDat
absolute encoders only) does
not operate on this feedback
type.
During the Measure the voltage
constant and Measure the motor
inertia tests, a torque is applied
to the motor. This error will occur
if the resulting motion is in the
opposite direction to the torque
(a positive torque should cause
positive velocity).

What to do
Check that there are no short circuits
between the U, V and W terminals
of the motor and that the motor power
cable is wired correctly.
This error will not normally occur
because Mint WorkBench will not
allow autotuning on unsupported
feedback types. Ie the combination of
Motor and Feedback device is not
supported by Mint Workbench.
The most common cause of this error
is an incorrectly wired or set up
feedback device (encoder or
resolver), or an incorrectly wired
motor. Select the Test the feedback
option. This will indicate if there is a
problem with the wiring or setup of
the drive and will automatically
compensate for certain wiring errors.
Note that the Test the feedback test
should ideally be run with the motor
disconnected from the load.
This error can also occur when
autotuning a motor connected to
some types of load. In particular,
loads with a lot of compliance (e.g.
belt drives) or torque offsets (e.g.
gravitational loading) can cause
problems for autotuning.
Another cause of the error may be
because the position feedback is
noisy, perhaps due to long cables on
resolver feedback systems, for
example. In either of these cases, it
may be necessary to manually tune
the system using the Fine-tuning tool.
