Dependen- Automatic restart requires constant ON command via a digital input wire link.
cy:
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 converter 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 converter will acknowledge (reset) faults i.e. it will reset a fault when the power is re-applied. This
means the converter must be fully powered down, a brownout is not sufficed. The converter will not run until
the ON command has been toggled.
P1210 = 2:
The converter will acknowledge the fault F3 at power on after blackout and restarts the converter. It is nec-
essary that the ON command is wired via a digital input (digital input).
P1210 = 3:
For these settings it is fundamental that the converter only restarts if it has been in a RUN state at the time
of the faults (F3, etc.). The converter will acknowledge the fault and restarts the converter after a brownout.
It is necessary that the ON command is wired via a digital input (digital input).
