10.12.2 Control and status words for encoders
Description
An encoder interface is defined in the PROFIBUS Profile for drive technology (PROFIdrive
V4.1). This interface defines a control and status word for encoders.
They are available in the following parameters:
● r0480[0] = G1_STW encoder 1 control word
● r0480[1] = G2_STW encoder 2 control word
● r0481[0] = G1_ZSW encoder 1 status word
● r0481[1] = G2_ZSW encoder 2 status word
The bit assignments of the control and status words for the encoders can be seen in the
following function diagrams:
● FP4720 (control word for encoders 1 and 2)
● FP4730 (status word for encoders 1 and 2)
For the description, see Chapter Control and status words for encoders (Page 399).
