2.2 List of parameters
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 acknowledgment 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, acknowledgment is immediate and when the line supply returns, the system is switched on.
If, between successfully acknowledging the line fault and the line supply returning, another fault occurs, then its
acknowledgment also causes the start counter to be decremented.
For p1210 = 26:
The start counter is decremented if after a successful fault acknowledgment, the on command is present.
p1212 Automatic restart delay time start attempts / AR t_wait start
Access level: 3
Can be changed: U, T
Unit 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.
p1213[0...1] Automatic restart monitoring time / AR t_monit
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.0 [s]
Description: Sets the monitoring time of the automatic restart (AR).
Index: [0] = Restart
[1] = Reset start counter
Dependency: Refer to: p1210, r1214
Notice: A change is only accepted and made in the state "initialization" (r1214.0) and "wait for alarm" (r1214.1).
After fault F07320 occurs, the switch-on command must be withdrawn and all of the faults acknowledged so that the
automatic restart function is re-activated.
Note: For index 0:
The monitoring time starts when the faults are detected. If the automatic acknowledgments are not successful, the
monitoring time runs again. If, after the monitoring time has expired, the drive has still not successfully started again
(flying restart and magnetizing of the motor must have been completed: r0056.4 = 1), then fault F07320 is output.
The monitoring is de-activated with p1213 = 0. If p1213 is set lower than the sum of p1212, the magnetizing time
p0346 and the additional delay time due to the flying restart, then fault F07320 is generated at each restart. If, for
p1210 = 1, the time in p1213 is set lower than in p1212, then fault F07320 is also generated at each restart.
The monitoring time must be extended if the faults that occur cannot be immediately and successfully acknowledged
(e.g. for faults that are permanently present).
In the case of p1210 = 14, 16, the faults which are present must be acknowledged manually within the time in
p1213[0]. Otherwise, fault F07320 is generated after the set time.
