• The selected servo parameter set
A parameter set describes the most important setting options for control purpose in the
servo.
It comprises, e.g., the following axis-specific/spindle-specific machine data:
31050 DRIVE_AX_RATIO_DENOM[n] Parameter set n for 0 to 5
31060 DRIVE_AX_RATIO_NUMERA[n] Parameter set n for 0 to 5
32200 POSCTRL_GAIN[n] Parameter set n for 0 to 5
32452 BACKLASH_FACTOR[n] Parameter set n for 0 to 5
32610 VELO_FFW_WEIGHT[n] Parameter set n for 0 to 5
32800 EQUIV_CURRCTRL_TIME[n] Parameter set n for 0 to 5
32810 EQUIV_SPEEDCTRL_TIME[n] Parameter set n for 0 to 5
32910 DYN_MATCH_TIME[n] Parameter set n for 0 to 5
36012 STOP_LIMIT_FACTOR[n] Parameter set n for 0 to 5
36200 AX_VELO_LIMIT[n] Parameter set n for 0 to 5

Dynamic criteria and feedforward control
With dynamic response criteria, it must be distinguished from where they were set:
• In the part program
or
• From a main-run interpolation (synchronized action or PLC default)
Note
Changes in the dynamic response made in a part program do not affect command axis or
PLC axis movements.
Changes from synchronized actions do not affect the movements from a part program.
Travel with feedforward control ON/OFF
The type of feedforward control and the path axes to which feedforward is to be applied are
determined:
• Programmable in the part program with FFWON/ FFWOF for axes selected using machine
data.
• Only indirectly programmable in synchronized actions (ASUB).
• Only indirectly programmable from the PLC (ASUB).
