3.4.2 First start for SFVC drive (suitable for crushers, conveyors, etc.)
In the SFVC vector control process, it is necessary to tune the inverter to the driven electric
motor!
A simplified example:
After you have correctly connected the V800 frequency converter according to chapter 1
and 2 and you have correctly connected the appropriate electric motor:
Set V800 parameters
P0.00=1
P0.01=1
P0.08= select the start-up time according to the load
P0.09= select the deceleration time according to the load
P2.01= power of the driven electric motor according to its nameplate
P2.02= nominal supply voltage of the electric motor according to its nameplate
P2.03= rated current of the electric motor according to its nameplate
P2.04= nominal frequency of the electric motor according to its nameplate
P2.05= rated speed of the electric motor according to its nameplate
Then set automatic tuning (if you have the drive decoupled - no load), enter dynamic tuning
P2.37=2 and press START. "StudY" lights up on the display and the drive starts. After the end
of the tuning process (autotuning), the set frequency appears on the display, e.g.: 50.00
If you already have the drive connected to the load, the direction of rotation of the electric
motor rotor is correctly set, but for certain reasons it is safer not to rotate the drive, enter
static tuning:
P2.37=1 and press START. "StudY" lights up on the display, but the drive does not start. The
electric motor shaft will only "twitch" slightly and there may be an intermittent "buzz" from
the motor (this is a natural tuning effect). After the end of the tuning process (autotuning),
the set frequency appears on the display, e.g.: 50.00.
3.5 Inverter operation
3.5.1 Power-on initialization
When the inverter is switched on, the system first initializes, the LED display shows "2000".
When the initialization is complete, the inverter is in the standby mode.
