Parameter Function
P1203[0...2] Search rate: flying start
[%]
Sets factor (in V/f mode only) by which the output frequency changes during flying start to synchronize
with turning motor. This value is entered in [%]. It defines the reciprocal initial gradient in the search se-
quence. P1203 influences the time taken to search for the motor frequency.
Example: For a motor with 50 Hz, 1350 rpm, 100 % would produce a maximum search time of 600 ms.
Note: A higher value produces a flatter gradient and thus a longer search time. A lower value has the opposite
effect.
