Re p1210 = 26:
The same as for p1210 = 6. For this mode, the switch-on command can be entered with a delay. The restart is
interrupted with either OFF2 or OFF3. Alarm A07321 is only displayed if the cause of the fault has been removed and
the drive is restarted by setting the switch-on command.
Description: Sets the start attempts of the automatic restart function for p1210 = 4, 6, 14, 16, 26.
Dependency: A change is only accepted and made in the state "initialization" and "wait for alarm".
Refer to: p1210
Notice: After fault F07320 occurs, the power-on command must be withdrawn and all of the faults acknowledged so that the
automatic restart function is re-activated.
After a complete power failure the start counter always starts with the counter value that applied before the power
failure, and decrements this start attempt by 1. If a further attempt to acknowledge is started by the automatic restart
function prior to power failure, e.g. when the CU remains active on power failure longer than the time p1212 / 2, the
fault counter will already have been decremented once. In this case, the start counter is thus decreased by the value
2.
Note: A start attempt starts immediately when a fault occurs. The start attempt is considered to been completed if the motor
was magnetized (r0056.4 = 1) and an additional delay time of 1 s has expired.
As long as a fault is present, an acknowledge command is generated in the time intervals of p1212 / 2. When
successfully acknowledged, the start counter is decremented. If, after this, a fault re-occurs before a restart has been
completed, then acknowledgement starts again from the beginning.
Fault F07320 is output if, after several faults occur, the number of parameterized start attempts has been reached.
After a successful start attempt, i.e. a fault/error has no longer occurred up to the end of the magnetizing phase, the
start counter is again reset to the parameter value after 1 s. If a fault re-occurs - the parameterized number of start
attempts is again available.
At least one start attempt is always carried out.
After a line supply failure, acknowledgement is immediate and when the line supply returns, the system is powered
up. If, between successfully acknowledging the line fault and the line supply returning, another fault occurs, then its
acknowledgement also causes the start counter to be decremented.
Re p1210 = 26:
The start counter is decremented if after a successful fault acknowledgement, the on command is present.
Description: Sets the delay time up to restart.
Dependency: This parameter setting is active for p1210 = 4, 6, 26.
For p1210 = 1, the following applies:
Faults are only automatically acknowledged in half of the waiting time, no restart.
Refer to: p1210
Notice: A change is only accepted and made in the state "initialization" and "wait for alarm".
Note: The faults are automatically acknowledged after half of the delay time has expired and the full delay time.
If the cause of a fault is not removed in the first half of the delay time, then it is no longer possible to acknowledge in
the delay time.
