Extended FunctionsFlying restart (vector)!WarningWhen the flying restart (p1200) function is active, the drive may still be acceleratedby the detection current despite the fact that it is at standstill and the setpoint is 0.For this reason, entering the area around the drive when it is in this condition cancause death, serious injury, or considerable material damage.NoteWith induction motors, the demagnetization time must elapse before the flyingrestart function is activated to allow the voltage at the motor terminals to decreaseotherwise high equalizing currents can occur when the pulses are enabled due toa phase short-circuit.Overview of important parameters (refer to the List Manual)p1082 Maximum speedp1200 Flying restart operating mode– 0: Flying restart inactive– 1: Flying restart is always active (start in the setpoint direction).– 2: Flying restart is active after: power-on, fault, OFF2 (start in the setpointdirection).– 3: Flying restart is active after: fault, OFF2.
