For speed monitoring, the feedback signal via incremental encoder can
either be supplied via input X8 or X9.
ƒ At input X8 you can only attach an incremental encoder with
TTL−levels.
ƒ Incremental encoders with HTL−level can only be connected to input
X9.
The incremental encoder signal can be output for slaves at the digital
frequency output X10.
The master frequency input (DFIN) and master frequency output (DFOUT)
are described in the chapter "Function library".
)
Note!
You can use maximally two of the three interfaces X8, X9, X10 at
the same time. This may lead to the fact that the incremental
encoder input cannot be activated or the master frequency input
or master frequency output does not work.
This does not apply if the input signal at X8 or X9 is directly
ƒ
output to master frequency output X10 (C0540 = 4 or 5).
To deactivate the master frequency input, the internal signal
ƒ
connection of function block DFIN to the following function
block must be removed. Remove the function block DFIN from
the processing table.
