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 inter-
rupted with either OFF2 or OFF3.
p1211 Automatic restart start attempts / AR start attempts
Access level: 3
Can be changed: U, T
Units group: -
Min
0
Description: Sets the start attempts of the automatic restart function for p1210 = 4, 6, 14, 16, 26.
Dependency: Refer to: p1210, r1214
Refer to: F07320
Caution: A change is only accepted and made in the state "initialization" (r1214.0) and "wait for alarm" (r1214.1).
Notice: After fault F07320 occurs, the power-on command must be withdrawn and all of the faults acknowledged so that the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 suc-
cessfully 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.
For p1210 = 26, the start counter is decremented if after a successful fault acknowledgement, the on command is
present.
p1212 Automatic restart delay time start attempts / AR t_wait start
Access level: 3
Can be changed: U, T
Units group: -
Min
0.1 [s]
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, r1214
Notice: A change is only accepted and made in the state "initialization" (r1214.0) and "wait for alarm" (r1214.1).
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.
