7.4 Positioning spindles (SPOS, M19 and SPOSA, WAITS)
Position master spindle (SPOS or SPOS[0]) or spindle number n
(SPOS[n]); the next NC block is not enabled until the position has
been reached.
Position master spindle (M19 or M[0]=19) or spindle number n
(M[n]=19); the next NC block is not enabled until the position has
been reached.
Position master spindle (SPOSA or SPOSA[0]) or spindle with number
n (SPOSA[n]); the next NC block is enabled, even if the position has
not been reached.
Switch over master spindle (M70) or spindle number n (Mn=70) to
axis operation. No defined position is approached. The NC block is
enabled after the switchover has been performed.
Motion end when "Exact stop fine" reached
End of positioning for specified spindle Sn
Motion end when "Exact stop coarse" reached
End of positioning for specified spindle Sn
End of motion when "IPO stop" is reached
End of positioning for specified spindle Sn
End of motion criterion from moment of application of braking ramp at
100% down to end of braking ramp at 0% and identical to IPOENDA.
IPOBKRA must be programmed in round parenthesis "()".
