For factory Setting, AO=10V when the output frequency is equal to
maximum frequency (defined by P134), i.e., equal to 66Hz.
Indication scale at the analog outputs (full scale =10V):
It configures the time constant of the analog inputs filter between 0
(without filtering) and 200ms.
Thus the analog input will have a response time equal to three time
constants. For instance, if the time constant is 200ms, and a step
is applied to the analog input, the response will be stabilized after
600ms.
