Programmable servo parameter block (SW 5.1 and higher)

Programming
SCPARA[<axis>]= <value>
Explanation of the commands
SCPARA
Axis
Value
Function
Using SCPARA, it is possible to program the parameter
block (consisting of MDs) in the part program and in
synchronized actions (previously only via PLC).
DB3n DBB9 Bit3
To prevent conflicts between the PLC-user request
and NC-user request, a further bit is defined on the
PLC–>NCK interface:
DB3n DBB9 Bit3 "Parameter block definition locked
through SCPARA".
