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
reference percentage
consider the
nel.
The assignment is done with the help of the parameters
734 and
eration
current component Isq.
The sources for the torque limits can be selected via the parameters
source, motor op.
Operation mode 736, 737
101 - Analog input MFI1A
Repetition frequency input
105 -
(F3)
110 - Fixed limit
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.
