Setting
Settings 1 to 3 search in both directions:
= 0: Flying start disabled
= 1: Flying start always active
= 2: Flying start active after power on, fault, OFF2
= 3: Flying start active after fault, OFF2
Settings 4 to 6 search only in the direction of the setpoint:
= 4: Flying start always active
= 5: Flying start active after power on, fault, OFF2
= 6: Flying start active after fault, OFF2
This parameter defines search current used for flying start.
Range: 10 to 200 (factory default: 100)
Note: Search current settings in P1202 that are below 30%
(and sometimes other settings in P1202 and P1203) may
cause motor speed to be found prematurely or too late, which
can result in F1 or F2 trips.
This parameter sets factor (in V/f mode only) by which the
output frequency changes during flying start to synchronize
with turning motor.
Range: 10 to 500 (factory default: 100)
Note: A higher value produces a flatter gradient and thus a
longer search time. A lower value has the opposite effect.
