2.2 List of parameters
Description: Displays the status word for the ramp-function generator (RFG).
Note: For bit 02:
The bit is the result of the OR logic operation - bit 00 and bit 01.
Description: Sets the operating mode for flying restart.
The flying restart allows the drive converter to be switched on while the motor is still rotating. In so doing, the drive
converter output frequency is changed until the actual motor speed/velocity is found. The motor then accelerates up
to the setpoint at the ramp-function generator setting.
Value: 0: Flying restart inactive
1: Flying restart always active (start in setpoint direction)
4: Flying restart always active (start only in setpoint direction)
Dependency: A differentiation is made between flying restart for U/f control and for vector control (p1300).
Flying restart, U/f control: p1202, p1203, r1204
Flying restart, vector control: p1202, p1203, r1205
For synchronous motors, flying restart cannot be activated.
Refer to: p1201
Refer to: F07330, F07331
Notice: The "flying restart" function must be used in cases where the motor may still be running (e.g. after a brief line supply
interruption) or is being driven by the load. The system might otherwise shut down as a result of overcurrent.
Note: For p1200 = 1, 4, the following applies:
Flying restart is active after faults, OFF1, OFF2, OFF3.
For p1200 = 1, the following applies:
The search is made in both directions.
For p1200 = 4, the following applies:
The search is only made in the setpoint direction.
For U/f control (p1300 < 20), the following applies:
The speed can only be sensed for values above approx. 5 % of the rated motor speed. For lower speeds, it is
assumed that the motor is at a standstill.
If p1200 is changed during commissioning (p0010 > 0), then it is possible that the old value will no longer be able to
be set. The reason for this is that the dynamic limits of p1200 have been changed by a parameter that was set when
the drive was commissioned (e.g. p0300).
