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
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.
101 - Analog input MFI1A
The source is the multifunctional input 1 in ana-
log Operation mode 452.
105 -
Repetition frequency input
(F3)
The frequency signal on the repetition frequency
input corresponding to
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.
