Specify spindle position
The spindle position is specified in degrees. Three spindle positions are possible for each
NC block. If nothing is specified, traversing automatically takes place as for DC. With
incremental dimensioning IC (INC), spindle positioning can take place over several
revolutions.

Position master spindle (SPOS) or spindle number n
(SPOS[n]); the next NC block is not enabled until the
position has been reached.
Position master spindle (M19) or spindle number n
(M[n]=19); the next NC block is not enabled until the
position has been reached.
Position master spindle with SPOSA or spindle 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 "()".
Wait for spindle position to be reached, spindle stop
after M5, spindle speed after M3/M4
WAITS applies to the master spindle, WAITS( ..., ...) for
the specified spindle numbers
Integers from 1 ... n of spindle number
Integers from 1 ... m of master spindle
nth Spindle number, 0 to max. spindle number
Channel identifier
Percentage specification 100-0% referred to the braking
ramp for block changes. If no % is specified, the current
value of the setting data is applied.
