SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Configures automatic restart function
Values: 0: Disabled
1: Trip reset after power on, P1211 disabled
2: Restart after mains blackout, P1211 disabled
3: Restart after mains brownout or fault, P1211 enabled
4: Restart after mains brownout, P1211 enabled
5: Restart after mains blackout and fault, P1211 disabled
6: Restart after mains brown- /blackout or fault, P1211 enabled
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 is 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 a long mains break, where the DC link has fully collapsed before the power is re-applied.
"Delay Time" is the time between attempts of quitting fault. The "Delay Time" of first attempt is 1 second, then it will
be doubled every next attempt.
The "Number of Restart Attempts" can be set in P1211. This is the number of restarts the inverter will try to quit
fault.
When faults are quit and after 4 seconds of no fault condition, "Number of Restart Attempts" will be reset to P1211
and "Delay Time" will be reset to 1 second.
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 a digital input (DI).
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 neces-
sary that the ON command is wired via a digital input (DI).
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 a digital input (DI).
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 a digital input (DI).
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 a digital input (DI). Setting 6 causes the motor to restart immedi-
ately.
Flying start must be used in cases where the motor may still be turning (e.g. after a short mains break) or can be
driven by the load (P1200).
