660 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
11.3.4 Stop oscillation movement at the reversal point
Function
Reversal point 1:
Every time the oscillation axis reaches reversal position 1, it must be stopped by means of
the override and the infeed movement started.
Application
The synchronized action is used to hold the oscillation axis stationary until partial infeed has
been executed. This synchronized action can be omitted if the oscillation axis need not wait
at reversal point 1 until partial infeed has been executed. At the same time, this
synchronized action can be used to start the infeed movement if this has been stopped by a
previous synchronized action which is still active.
Programming
WHENEVER $AA_IM[oscillation axis] == $SA_OSCILL_REVERSE_POS1[oscillation axis]
DO $AA_OVR[oscillation axis] = 0 $AA_OVR[infeed axis] = 100
Explanation of system variables:
$AA_IM[oscillation axis]: Current position of oscillation axis
$SA_OSCILL_REVERSE_POS1[oscillation axis]: Reversal point 1 of the oscillation axis
$AA_OVR[oscillation axis]: Axial override of the oscillation axis
$AA_OVR[infeed axis]: Axial override of the infeed axis
Function
Reversal point 2:
Every time the oscillation axis reaches reversal position 2, it must be stopped by means of
the override 0 and the infeed movement started.
Application
The synchronized action is used to hold the oscillation axis stationary until partial infeed has
been executed. This synchronized action can be omitted if the oscillation axis need not wait
at reversal point 2 until partial infeed has been executed. At the same time, this
synchronized action can be used to start the infeed movement if this has been stopped by a
previous synchronized action which is still active.
