Acknowledges all When p1210 = 1, faults that are present are
faults without acknowledged automatically when their cause is rectified.
restarting If further faults occur after faults have been 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 acknowledge-
ment and a new fault must be at least 1s.
For p1210 = 1, fault F07320 is not generated if the
acknowledge attempt failed – for example because the
faults occurred too frequently.
Automatic restart For p1210 = 4, an automatic restart is only carried-out if in
after line supply addition fault F30003 occurred at the Motor Module or
failure, no there is a high signal at binector input p1208[1], or in the
additional start case of an infeed drive object (x_Infeed) F06200 has
attempts occurred. If additional faults are present, then these faults
are also acknowledged and when successfully
acknowledged, the starting attempt is continued. When
the 24 V power supply of the CU fails, this is interrupted as
a line supply failure.
Restart after any When p1210 = 6, an automatic restart is carried out after
fault with additional any fault or when p1208[0] = 1. If the faults occur one after
start attempts the other, then the number of start attempts is defined
using p1211. Monitoring over time can be set using p1213.
