18.5.3.3 Limit value sources

The limitation of the frequency can be done by setting fixed values and by linking to an analog input
parameter. The analog value is limited via parameters

Speed controller

The actual speed source is selected via parameter
Speed Sensor 1 is used as the source of actual speed. If Speed Sensor 2 of an extension module is
to deliver the actual value signal for the speed controller, Speed Sensor 2 must be selected as the
source. Alternatively, the speed controller can derive the actual speed value from the machine model
in in Configurations 410, 411 and 430 (

Parameter Configuration
The actual speed source is speed sensor 1 of the basic device (factory
setting).
The actual speed source is speed sensor 2 of an extension module.
The speed controller receives the calculated actual speed value from the
machine model. Can be set in configurations 4xx and 6xx.
Speedtracking by comparison between the calculated machine model and
