Fixed reference values

The fixed reference values are to be parameterized as fixed frequencies or fixed per-
centages according to the configuration and function.
The signs of the fixed reference values determine the direction of rotation. A positive
sign means a clockwise rotation; a negative sign means an anticlockwise rotation.
The direction can only be changed via the sign if the
475 or
source
mode with sign (+/-). The direction of rotation can also be stated with the digital
signal sources assigned to the parameters
clockwise
The fixed reference values are to be parameterized in four data sets and are assigned
to further sources via the reference value channel. The use of the functions

By combining the logic states of the fixed frequency change-over modes 1 and 2,
fixed frequencies 1 through 4 can be selected:

If an optional expansion module with digital inputs is installed additional fixed fre-
quencies can be selected. In this case refer to the instruction manual of the expansion
module.
