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 a very short mains break, where the DC link has not fully collapsed before the power
is reapplied.
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 power 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 F3 at power on after blackout and restarts the inverter. It is neces-
sary that the ON command is wired via a digital input (digital input).
P1210 = 3:
For these settings it is fundamental that the inverter only restarts if it has been in a RUN state at the time of
the faults (F3, etc.). The inverter will acknowledge the fault and restarts the inverter after a brownout. It is
necessary that the ON command is wired via a digital input (digital input).
P1210 = 4:
For these settings it is fundamental that the inverter only restarts if it has been in a RUN state at the time of
the fault (F3). The inverter will acknowledge the fault and restarts the inverter after a brownout. It is neces-
sary that the ON command is wired via a digital input (digital input).
