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 acceleration.

; Acceleration selection in accordance with fast input 1 ($A_IN[1]): 
N53 ID=1 WHEN $A_IN[1] == 1 DO $AC_PATHACC = 2.*$MA_MAX_AX_ACCEL[X] 
 
; Test override profile (simulates external intervention): 
N54 ID=2 WHENEVER ($AC_TIMEC > 16) DO $AC_OVR=10 
N55 ID=3 WHENEVER ($AC_TIMEC > 30) DO $AC_OVR=100
