Note
Start of a startup attempt
A startup attempt starts immediately when the fault occurs.
The faults are acknowledged automatically at intervals of half the waiting time p1212.
Following successful acknowledgement and restoration of the voltage, the system is
automatically powered up again.
The startup attempt has been successfully completed if the flying restart and the motor
magnetization (induction motor) have been completed (r0056.4 = 1) and one additional
second has expired. The startup counter is not reset to the initial value p1211 until this point.
If additional faults occur between successful acknowledgement and the end of the startup
attempt, then the startup counter, when it is acknowledged, is also decremented.
Automatic restart monitoring time (p1213)
● p1213[0] = Monitoring time for restart
The monitoring time starts when the faults are detected. If the automatic
acknowledgements are not successful, the monitoring time will continue. If the drive has
not successfully restarted by the time the monitoring time expires (flying restart and motor
magnetization must have been completed: r0056.4 = 1), fault F07320 is output.
The monitoring is deactivated with p1213 = 0. If p1213 is set to a value lower than the
sum of p1212, the magnetization time r0346 and the additional delay time due to flying
restart, then fault F07320 will be generated on every restart attempt. If, for p1210 = 1, the
time in p1213 is set to a value lower than p1212, then fault F07320 will also be generated
on every restart attempt.
The monitoring time must be extended if the faults that occur cannot be immediately and
successfully acknowledged (e.g. when faults are permanently present).
For p1210 = 14, 16 manual acknowledgement of the pending fault must take place within
the time in p1213[0]. Otherwise the fault F07320 is generated after the time set.
● p1213[1] = Monitoring time for resetting the starting counter
The starting counter (see r1214) is only reset to starting value p1211 once the time in
p1213[1] has expired after a successful restart. The delay time is not effective for error
acknowledgment without an automatic restart (p1210 = 1). If the power supply fails
(blackout), the wait time only starts once the power has been restored and the Control
Unit is ramped up. The starting counter is reset to the starting value p1211, if F07320
occurred, the switch-on command is recalled and the fault acknowledged.
If starting value p1211 or mode p1210 is changed, the starting counter is immediately
updated.
