17.5.4.2 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
518 and
Maximum reference percentage
519, but does not
consider the
Gradient percentage ramp
477 of the reference percentage value chan-
nel.
The assignment is done with the help of the parameters
Isq limit source motor op-
eration
734 and
Isq limit source generator operation
735 for the torque-forming
current component Isq.
The sources for the torque limits can be selected via the parameters
Torque limit
source, motor op.
736 and
Torque limit source generator op.
737.

105 - 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.
