SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
4.2.2 Parameter set changeover
It is possible to switch between 8 different parameter sets. Data which are as-
signed to specific parameter sets are identified by an [n] in the string code [0-7].
The request is made from the PLC by means of IS “Select drive parameter set”
DB 31-61 DBB 21 bits 0-2. They are predominantly controller and filter data
that can be switched over as a function of parameter set.
The status is interrogated by means of IS “Active drive parameter set” DB
31-61 DBB 93 bits 0-2.
Section 4.15 contains a complete parameter list with the attributes for each pa-
rameter.
