Control and status words for encoders
The process data for the encoders is available in various telegrams. For example, telegram 3
is provided for speed control with 1 position encoder and transmits the process data of
encoder 1.
The following process data is available for the encoders:
● Gn_STW encoder n control word (n = 1, 2)
● Gn_ZSW encoder n status word
● Gn_XIST1 encoder n act. pos. value 1
● Gn_XIST2 encoder n act. pos. value 2
Note
Encoder 1: Motor encoder
suring system
Example of encoder interface
Figure 10-4 Example of encoder interface (encoder-1: Two actual values, encoder-2: One actual
value)
Encoder n control word (Gn_STW, n = 1, 2)
The encoder control word controls the encoder functions.
See function diagram [4720].
