Automatic restart

P1210 Automatic restart
CStat: CUT
P-Group: FUNC
Configures automatic restart function
Possible Settings:
0 Disabled
1 Trip reset after power on,
2 Restart after mains blackout,
3 Restart after mains brownout or fault,
4 Restart after mains brownout,
5 Restart after mains blackout and fault,
6 Restart after mains brown- /blackout or fault
Dependency:
Automatic restart requires constant ON command via a digital input wire link.
Caution:
P1210 > 2 can cause the motor to restart automatically without toggling the ON command !
Notice:
A "mains brownout" is where the power in interrupted and re-applied before the display on the BOP (if one
is fitted to the inverter) has gone dark (a very short mains break where the DC link has not fully collapsed).
A "mains blackout" is where the display has gone dark (a long mains break where the DC link has fully
collapsed) before the power is re-applied.
P1210 = 0:
Automatic restart is disabled.
P1210 = 1:
The inverter will acknowledge (reset) faults i.e. it will reset a fault when the is re-applied. This means the
inverter must be fully powered down, a brownout is not sufficed. The inverter will not run until the ON
command has been toggled.
P1210 = 2:
The inverter will acknowledge the fault F0003 at power on after blackout and restarts the drive. It is
necessary that the ON command is wired via digital input (DIN).
P1210 = 3:
For these settings it is fundamental that the drive only restarts if it has been in a RUN state at the time of the
faults (F0003, etc.). The inverter will acknowledge the fault and restarts the drive after a blackout or
bronwout. It is necessary that the ON command is wired via digital input (DIN).
P1210 = 4:
For these settings it is fundamental that the drive only restarts if it has been in a RUN state at the time of the
fault (F0003). The inverter will acknowledge the fault and restarts the drive after a blackout or bronwout. It is
necessary that the ON command is wired via digital input (DIN).
P1210 = 5:
The inverter will acknowledge the faults F0003 etc. at power on after blackout and restarts the drive. It is
necessary that the ON command is wired via digital input (DIN).
P1210 = 6:
The inverter will acknowledge the faults (F0003 etc.) at power on after blackout or brownout and restarts the
drive. It is necessary that the ON command is wired via digital input (DIN). Setting 6 causes the motor to
restart immediately.
