Limit value sources
As an alternative to limiting the output values by a fixed value, linking to an analog input value is
also possible. The analog value is limited via parameters
Minimum Reference Percentage

,
Maximum Reference Percentage

, but does not consider
the Gradient Percentage Ramp
477
of
the reference percentage channel.
The assignment is done via parameter

Repetition frequency input
(F3)
The frequency signal on the repetition frequency input
corresponding to Operation Mode
496.
110 - Fixed Limit
The selected parameter figures for limiting the speed controller
are taken into account.
The limit values and assignment to different limit value sources are data set related in
the configurations. The use of the data record change-over demands an examination
of the parameters in question.
