The starting attempt has been successfully completed if the flying restart and the motor
magnetization (induction motor) have been completed (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 acknowledgement 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 acknowledgements
are not successful, the monitoring time runs again. If the drive has not successfully started
again after the monitoring time has expired (flying restart and motor magnetization must
have been completed: r0056.4 = 1), fault F07320 is output. The monitoring is de-activated
with p1213 = 0.
If p1213 is set lower than the sum of p1212, the magnetization time r0346 and the additional
delay time due to flying restart, then fault F07320 is generated at each restart. If, for p1210 =
1, the time in p1213 is set lower than p1212, then fault F07320 is also generated at 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 for vector and infeed drive object
– Automatic restart: Set mode (p1210).
– Flying restart: Activate function (p1200).
2. Set starting attempts (p1211).
3. Set waiting times (p1212, p1213).
4. Check function.
