Functions
6.9 Technological functions
Since the function is not restricted to line supply faults, it can also be used to automatically
acknowledge faults and restart the motor after any tripping. To allow the drive to be switched
to a motor shaft that is still rotating, the "flying restart" function must be activated via P1200.
When the "automatic restart" function is active (P1210 > 1), a motor can restart
automatically once the power has been restored. This is particularly critical if it is incorrectly
assumed that the motors have been shut down after a long power failure.
For this reason, death, serious injury, or considerable material damage can occur if
personnel enters the working area of motors in this condition.
Commissioning the automatic restart
1. Parameterizing the automatic restart using P1210
2. Set the number of start attempts via P1211.
3. If, for an automatic restart, the inverter is to be connected to an already rotating motor,
then the 'flying restart' function should also be activated using P1200.
4. Make sure that this functions properly.
