Exception: a mechanical coupling ensures that all of the motors always operate with the same
speed.

Parameter Description
p0346 Motor excitation build up time
Wait time between switching on the motor and enabling the ramp-function generator.
p0347 Motor de-excitation time
Within the motor de-excitation time, after an OFF command, the inverter prevents the
induction motor from being switched on again.
When using a reluctance motor, the inverter ignores the motor de-excitation time.
p1201 Flying restart enable signal source (factory setting: 1)
Defines a control command, e.g. a digital input, which enables the flying restart function.
p1202 Flying restart search current (Factory setting depends on the Power Module)
Defines the search current with respect to the magnetizing current (r0331), which flows
in the motor during the flying restart.
p1203 Flying restart search current factor (Factory setting depends on the Power Module)
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).
