9.2.3.4 Control and status words for encoder
Description
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
Encoder 2: Direct measuring system
