1. Set the speed reference to “0” (zero) using the assigned source
(HIM or analog potentiometer). Refer to
for more information on speed reference sources.
2. View Par 385 [Speed Ref Out] and verify that the value is “0”.
3. Press the Start button on the HIM and slowly increase the speed
reference until full speed is reached (viewed in Par 385 [Speed Ref
Out] ).
4. If using a four quadrant (regenerative) drive, press the Direction
button on the HIM and verify that the motor ramps down to “0”
speed and then to full speed in the opposite direction.
5. Press the Stop button on the HIM and verify that the drive ramps to
“0” speed and stops.
Auto Tuning Faults
Following is a list of faults that may display during the speed regulator
auto tuning test. In some cases, the drive’s control circuits may detect a
value(s) that is out of range for the configuration settings during the
speed regulator auto tuning test. In these cases, make the suggested
adjustments and repeat the test. If the fault occurs again, complete the
procedures beginning on
.
Fault
No. Description
Action
STune
Overspeed

high at zero speed to complete
the speed regulator auto tuning
procedure.
Decrease the load torque, where
applicable, and repeat the auto
tune procedure.

33% of the lower of the values in
Par 45 [Max Ref Speed] or Par 3
[Max Speed Fwd] or Par 4 [Max
