3.2.1 Example of how to select a configuration
The direction of rotation of the motor in a system is to be
determined by the sign of the analog set-value (0...+10V for CW
rotating field, 0...10V for CCW rotating field).
A closed-loop speed control is to be used, for which a DC tacho
serves as feedback. A set-value 2 is not used.
The corresponding configuration can be determined as follows:
The table "Closed-loop speed control" contains two configurations
where the set-value 1 is provided analog as bipolar set-value.
These are the parameters -11- and -13-. The desired closed-loop
speed control using DC tachogenerator is possible with parameter
-11-. The set-value 2 via terminals 1 and 2 is active, but is not
required. Therefore its influence must be set to zero as protection
from set-value couplings. Please observe the notes on page 66.
