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).
