5.6 Digital frequency output X9 (Option)
The connection of drives via digital frequency allows a simple and
precise control of multi-motor systems. The digital frequency output
X9 can be used here as digital frequency encoder, e.g. for parallel
or slave drives.

Depending on the relationship of the drive controlled via X9, you
can program under C008 if the input signals at X5 are to be output
unchanged or if an internal set-value signal is to be processed.
Internal set-value sources are:
•
Main set-value (Set-value 1/JOG frequency)
•
Ramp generator output (main set-value)
•
Total set-value (total of ramp generator outputs)
If you have selected an internal set-value signal as digital
frequency, you can also program its setting range under C030. The
frequency of the output signals results from
Output freq. = set-value signal
⋅
max. field freq. (C011)
⋅
constant (C030)
Please note that when processing the selected set-value signal
minor conversion errors may be possible.
