Siemens SINAMICS S120 Function Manual page 337

The startup 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 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 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 deactivated
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. p1210 = 1
prevents a restart 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. Activate the function for drive objects "SERVO", VECTOR or X_INF (all drive objects
"Infeed"; i.e. A_INF, B_INF, S_INF).
– Automatic restart: Set mode (p1210).
– Flying restart (only for "VECTOR"): Activate function (p1200).
2. Set the startup attempts (p1211).
3. Set the wait times (p1212, p1213).
4. Check the function.
Exceptions
There are faults, where after they have occurred, an automatic restart would be dangerous
or is undesirable. Enter the numbers of these faults into p1206[0...9]. The automatic restart is
suppressed if one of these faults occurs. After the cause of the fault has been removed, the
drives must be switched-on in another way.
