    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

yes, you can set different dead values of engines according to runtime
conditions (see also [1]). I think that the easiest way is to add PyRunned
to O.engines with iterPeriod=1, checking some constidion and switching
dead=True/False if the condition is met.

But I think that amplitude is not very good trigger, as it is an attribute
of the HarmonicRotationEngine and is constant (if you don't change it from
outside).

cheers
Jan

PS: sorry for very quick answer due to lack of time, in case it is not
clear, I will try to explain more in detail tomorrow
