Advanced settings
Flying restart enable signal source (factory setting: 1)
Defines a control command, e.g. a digital input, through which the flying restart function
is enabled.
Flying restart search current (Factory setting for Power Module PM230: 90 %. Factory
setting for PM240, PM250 and PM260: 100%)
Defines the search current with respect to the motor magnetizing current (r0331), which
flows in the motor while the flying restart function is being used.
Flying restart search speed factor (Factory setting for Power Module PM230: 150 %.
Factory setting for PM240, PM250 and PM260: 100%)
The value influences the speed with which the output frequency is changed during the
flying restart. A higher value results in a longer search time.
If the inverter does not find the motor, reduce the search speed (increase p1203).
