See the control chain diagrams 756 and 757.
- / real32Displays the used frequency reference before ramping.
See the control chain diagram on page 757.
Frequency ref ramp
input
28.1
This parameter is read-only.
- / -Frequency reference before ramping. For scaling, see
parameter 46.2.
-598.00 ... 598.00 Hz
- / real32Displays the final frequency reference (after selection,
limitation and ramping). See the control chain diagram
on page 757.

This parameter is read-only.
- / -Final frequency reference. For scaling, see parameter
46.2.
-598.00 ... 598.00 Hz
P.9.21 / uint32Selects frequency reference source 1.
Two signal sources can be defined by this parameter
and 28.12 Frequency ref2 source. A digital source
Frequency ref1
source
28.11
selected by 28.14 Frequency ref1/2 selection can be
used to switch between the two sources, or a
mathematical function (28.13 Frequency ref1 function)
applied to the two signals to create the reference.
