4.2.1
Path velocity characteristic
Key statement
An excerpt from a part program is provided below, together with the associated acceleration
characteristic, by way of an example. These are used to illustrate how the path velocity can
be adapted to take account of various events and the resulting change in jerk.
Part program (excerpt, schematic)
; Setting of path acceleration and path jerk in the event of external intervention:
N0100 $AC_PATHACC = 0.
N0200 $AC_PATHJERK = 4. * ($MA_MAX_AX_JERK[X] + $MA_MAX_AX_JERK[Y]) / 2.
; Synchronized actions for the purpose of varying the override (simulates external
intervention):
N53 ID=1 WHENEVER ($AC_TIMEC > 16) DO $AC_OVR=10
N54 ID=2 WHENEVER ($AC_TIMEC > 30) DO $AC_OVR=100
