Detailed Description
2.3 Feedrate control
Feeds (V1)
2-48 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
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>
Where
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.
...
Constraints
Different end-of-motion criteria will affect how quickly or slowly part program blocks are
completed. This can have side effects for technology cycles and PLC user parts.
The PLC user program must be expanded if the servo parameter set is to be changed
both inside a part program or synchronous action and the PLC.
After POWER ON, the following initial settings are made:
Percentage acceleration override for all single-axis
interpolations
100%
End-of-motion criterion for all single-axis interpolations
FINEA
Servo parameter set defined by the NC 1
