Drive functions
7.2 Basic functions
Starting attempts (p1211) and delay time (p1212)
p1211 is used to specify the number of starting attempts. The number is internally
decremented after each successful fault acknowledgment (line supply voltage must be re-
applied). Fault F07320 is signaled if the number of parameterized startup attempts is
exceeded.
When p1211 = x, x + 1 starting attempts are made.
Note
A start attempt immediately starts when the fault occurs.
The faults are automatically acknowledged in intervals of half the delay time p1212.
After successful acknowledgment and voltage recovery, the system is automatically powered
up again.
The starting attempt is considered to have been successfully completed once motor
magnetization (induction motor) is complete (r0056.4 = 1) and one additional second has
expired. The starting counter is only reset back to the initial value p1211 after this time.
If additional faults occur between successful acknowledgment and the end of the startup
attempt, then the startup counter, when it is acknowledged, is also decremented.
Monitoring time line supply return (p1213)
The monitoring time starts when the faults are detected. If the automatic acknowledgments
are not successful, the monitoring time runs again. If the drive has not successfully restarted
once the monitoring time has expired (motor magnetization must have been completed:
r0056.4 = 1), fault F07320 is output. The monitoring is deactivated with p1213 = 0.
If a fault is pending, fault F07320 will be generated on every restart attempt if the time
defined in p1213 has expired. If p1210 > 1 and the time in p1213 is set 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).
Commissioning
1. Activating the function
2. Set starting attempts (p1211).
3. Set delay times (p1212, p1213).
4. Check function.
