Chapter 3 Operation
46
In three-level state, if the parameter is not flashing, said the function code cannot be
modified, possible reasons are:
1) The function code parameters cannot be modified. Such as the actual testing
parameters, operation records, etc.;
2) The function code in the running state cannot be modified.
3.3.2 Fault RESET
After the failure of the inverter, the inverter will be prompted to related fault information.
User can press STOP key on the keyboard or terminal function to conduct the fault reset
(P5), after fault reset the inverter is in the standby mode. If the inverter is in fault state, the
user does not carry on the fault reset, the inverter is in the running to protect state and can't
run.
3.4 First start
3.4.1 First start for V/F drive (suitable for fans, pumps, etc.)
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=2
P0.01=0
P0.08= select the start-up time according to the load
P0.09= select the deceleration time according to the load
P1.10= 0 if you are stopping small inertias
P1.10= 1 if you are stopping large inertias, e.g. large fan
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
P4.01= increase in torque (use for harder start-up (preferably 0.0 = automatic)
