Without considering a fragmentation or an error, the parameter channel
when
writing a parameter is made up of:
Control word
Index Sub-index Data

S
2 bytes 2 bytes 2 bytes max. 80

Status word

Without considering a fragmentation, the parameter channel when
reading a parameter is made up of:

The control unit defines the basic setting and the drive responds with the
identifier (2 bytes) of the supported parameter channel format; in this
case with 01V00.

The control unit reads the operating data of parameter S-0-0057. It is a
double word, fragmentation therefore is not necessary.
The value is 100.
Parameter mapping:
•
index = 2039h
•
sub-index = 7h
