p1213[0...1] Automatic restart, monitoring time / AR t_monitoring
Access level: 3
Can be changed: U, T
Units group: -
Min
0.0 [s]
Description: Sets the monitoring time of the automatic restart (AR).
Index: [0] = For restart
[1] = To reset the start counter
Dependency: Refer to: p1210, r1214
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Notice: After fault F07320 occurs, the power-on command must be withdrawn and all of the faults acknowledged so that the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.
Note: Index 0:
The monitoring time starts when the faults are detected. If the automatic acknowledgements 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 acknowl-
edged (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 index 0. Otherwise, fault F07320 is generated after the set time.
Index 1:
The start counter (refer to r1214) is only set back to the starting value p1211 if, after successful restart, the time in
p1213 index 1 has expired. The delay time is not effective for fault acknowledgement without automatic restart
(p1210 = 1). After a power failure (blackout) the delay time only starts after the line supply returns and the Control
Unit boots. The start counter is set to p1211, if F07320 occurred, the power-on command is withdrawn and the fault
is acknowledged.
The start counter is immediately updated if the starting value p1211 or the mode p1210 is changed.
For p1210 = 26, the fault must have been successfully acknowledged and the switch-on command issued within the
time in p1213, index 0. Otherwise, fault F07320 is generated after the set time.
