SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
Note: When p1200 = 1, 4: Flying restart is active after faults, OFF1, OFF2, OFF3.
When p1200 = 1: The search is made in both directions.
When p1200 = 4: 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).
Description: Sets the signal source to enable the "flying restart" function.
Dependency: Refer to: p1200
Note: Withdrawing the enable signal has the same effect as setting p1200 = 0.
Description: Sets the search current for the "flying restart" function.
The value is referred to the motor magnetizing current.
Dependency: Refer to: r0331
Caution: An unfavorable parameter value can result in the motor behaving in an uncontrollable fashion.
Note: In U/f control mode, the parameter serves as a threshold value for establishing the current at the beginning of the
flying restart function. When the threshold value is reached, the prevailing search current is set dependent upon the
frequency on the basis of voltage inputs.
Reducing the search current can also improve flying restart performance (if the system moment of inertia is not very
high, for example).
