set the V VW.
6. Parameterization of the V VW control: browsing the “STARTUP” menu, set parameters P0399, P0400, P0401,
P0402, P0403, P0404 and P0407 according to the data on the motor nameplate. If some of those data are
not available, insert the approximate value by calculation or similarity to WEG standard motor – see
Table 10.1
on page 10-4 .
7. Self-Tuning of the V VW control: The self-tuning is activated by setting P0408 = 1. In this process, the inverter
applies DC to the motor to measure the stator resistance, while the HMI bar graph shows the progress of the
self-tuning. The self-tuning process can be interrupted at any time by pressing the “
” key.
8. End of the Self-Tuning: at end of the self-tuning, the HMI returns to the browsing menu, the bar displays the
parameter programmed by P0207 again and the stator resistance measured is stored in P0409. On the other
hand, if the self-tuning fails, the inverter will indicate a fault. The most common fault in this case is F0033,
which indicates error in the estimated stator resistance. Refer to
Chapter 15 FAULTS AND ALARMS on page
15-1 .
For applications:
„
That can use the factory default programming of the analog and digital inputs and outputs, use the HMI
“BASIC” menu.
„
That require just the analog and digital inputs and outputs with programming different from the factory default,
use the HMI “I/O” menu.
„
That require functions such as Flying Start, Ride-Through, DC Braking, Rheostatic Braking, etc., access and
modify the parameter of those functions in the HMI “PARAM” menu. For further information on the HMI menus,
refer to
Chapter 5 PROGRAMMING BASIC INSTRUCTIONS on page 5-1 .
