In the case of a locked parameter block for
SCPARA, an error message is produced if
programmed.
The current parameter block can be polled using the
system variables $AA_SCPAR[<axis>].
Additional notes
•
Up to SW 5.1, the servo-parameter block can be
specified only by the PLC (DB3n DBB9 Bit0–2).
For G33, G331 and G332, the most suitable
parameter block is selected by the control.
•
If the servo-parameter block is to be changed
both in a part program and in a synchronized
action and the PLC, the PLC-application
program mst be extended.
