			acknowledged, then these are also again
			automatically acknowledged. A minimum time of
			p1212 + 1s must expire between successful fault
			acknowledgement and a fault re-occurring if the
			signal ON/OFF1 (control word 1, bit 0) is at a HIGH
			signal level. If the ON/OFF1 signal is at a LOW
			signal level, the time between a successful fault
			acknowledgement and a new fault must be at least
			1s.

			acknowledge attempt failed (e.g. because the faults
			occurred too frequently).

			time can be set using p1213.

Starting attempts (p1211) and waiting time (p1212)

p1211 is used to specify the number of starting attempts. The number is internally decremented after each successful fault acknowledgement (line supply voltage must be re- applied or the infeed signals that it is ready. Fault F07320 is signaled if the number of parameterized startup attempts is exceeded.

When p1211 = x, x + 1 starting attempts are made.

Note

A start attempt immediately starts when the fault occurs.

The faults are automatically acknowledged in intervals of half the waiting time p1212.

After successfully acknowledgment and the voltage returns, then the system is automatically powered-up again.
