Programmable servo parameter set
SCPARA[Axis] = ...
SCPARA[axis]= ... can be used to program the parameter set (consisting of MDs) in the
part program and in synchronized actions (previously, this could only be done via the PLC).
Axis = Channel axis name (X, Y ....), spindle (S1, ...)
SCPARA[Axis]=
<value>

e
Value = Desired parameter set (1≤ value ≤ 6)
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 set selection by SCPARA disabled".
The PLC user is thereby able to set up a structured sequence when using PLC parameter
switchover and entries from synchronized actions or part programs simultaneously.
On a change of bit 3 (0 ⇒ 1 or 1 ⇒ 0), the entry is written to bits 0 - 2.
Note
If parameter set selection via SCPARA is disabled, there is no error message if the latter is
programmed nevertheless.
The current parameter set can be scanned by system variable $AA_SCPAR[Axis].
Example:
...
N100 SCPARA[X]=3
; The 3rd parameter set is selected for axis X.
