Description
Position at reversal point 1
Position at reversal point 2
Stop time at reversal point 1
Stop time at reversal point 2
Feed velocity of oscillation axis
Number of sparking-out strokes
Position after sparking-out strokes/at end of oscillation move‐
ment
Control screen form for oscillation
Oscillation movement ON/OFF
Position that is approached after oscillation before reversal
point 1, if activated in SD43770:
digital input (Boolean)
digital output (Boolean)
analog input (Boolean)
analog output (Boolean)
comparator inputs (Boolean)
actual position PCS axis (real)
actual position BCS axis (real)
Actual position MCS axis (IPO setpoints) (real)
With $AA_IM[S1] setpoints for spindles can be eval‐
uated. Modulo calculation is used for spindles and
rotary axes, depending on machine data
$MA_ROT_IS_MODULO and $MA_DIS‐
PLAY_IS_MODULO.
Breaking position after external oscillation reversal
when approaching reversal point 1
Breaking position after external oscillation reversal
when approaching reversal point 2
