Programmable servo parameter set (SCPARA)
In the part program / synchronized action, the servo parameter set can be specified using
SCPARA.
Syntax
SCPARA[<axis>] = <parameter set number>
Meaning
SCPARA:
<axis>:
<parameter set number>:
Note
The activation of the parameter set specified using SCPARA can be suppressed from the PLC
user program:
DB31,... DBX9.3 = 1 (parameter set specification disabled by SCPARA)
In this case, no message is displayed.
The number of the active parameter set can be read using the system variable
$AA_SCPAR.
Supplementary conditions
Different end-of-motion criteria
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.
Parameter set change
The PLC user program must be expanded if the servo parameter set is to be changed both
inside a part program or synchronized action and the PLC.
Power On
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: 1
Mode change
When the operating mode is changed from AUTOMATIC to JOG, the programmed dynamic
response changes remain valid.
