Programmable singleaxis dynamic response
Single axes
Single axes can be programmed in the part program, in synchronized actions and via the PLC:
Part program:
Synchronized actions:
PLC:
Dynamic response
The dynamic response of an axis is influenced by:
•
MD32060 $MA_POS_AX_VELO (positioning axis velocity)
The effective positioning axis velocity can be changed:
-
Part program/synchronized action: Axial feedrate FA or percentage feedrate override OVRA
-
PLC: Specification of FRate or overwriting the axial override
•
MD32300 $MA_MAX_AX_ACCEL (maximum axis acceleration)
The effective maximum axis acceleration can be changed:
-
Part program indirectly: Writing the machine data with subsequent NewConfig
-
Part program directly: Percentage acceleration override ACC
-
Synchronized actions indirectly: Writing the machine data and initiating an ASUB for the activation of
NewConfig
-
Synchronized actions directly: Percentage acceleration override ACC (cannot be preset by the PLC).
Via the PLC, the same options apply as in synchronized actions.
•
Commands: BRISKA, SOFTA, DRIVEA, JERKA
Cannot be programmed in synchronized actions (only directly using ASUB).
Cannot be specified by the PLC (only indirectly via ASUB).
•
Active servo parameter set
The active parameter set can be changed:
-
Part program/synchronized action: SCPARA
-
PLC: DB31,... DBX9.0 - 9.2 (controller parameter set)
