In case of issues occurred in the above step, try to tune the parameters below. Refer
to
ACS580MV Troubleshooting manual
(2UBB005092) for more information.
a. 21.02 Magnetization time
b. 21.30 Flystart current level
c. 21.31 Flystart flux ramp time
d. 21.32 Flystart frequency min
e. 21.33 Flystart frequency ramp time
f. 21.34 Flystart reverse enable
g. 21.35 Flystart speed detect curr level
h. 21.37 Flystart Iq ctrl filt time
i. 21.38 Flystart Iq ctrl Kp
j. 21.39 Flystart Iq ctrl Ki

If Flystart doesn’t perform negative speed search.
When motor is stopped with some load and motor is rotating in the negative direction.
Run the motor again with Automatic start mode (Par 21.19 scalar start mode =
Automatic), speed scan is performed and small positive speed is found even though
motor is rotating in negative direction. And then:
a. No negative speed scan
.
b. Flux reference is ramped assuming that the motor is rotating on the small positive
speed.
c. Motor cannot accelerate to the given reference. Motor stall warning is activated.
The parameters can be tuned to achieve the correct behavior by:
a. Decrease the Par 21.35 Flystart speed detect curr level to 0.4 or lower (0.3 or 0.2).
b. Decrease the Par 21.33 Flystart frequency ramp time.
