NC programming
Programming Manual, 12/2019, 6FC5398-2EP40-0BA0
Set the master spindle (M19 or M0=19) or spindle with the number <n> (M<n>=19)
to the angular position preset with SD43240 $SA_M19_SPOS with the position
approach mode preset in SD43250 $SA_M19_SPOSMODE.
The NC block is not enabled until the position has been reached.
Switch the master spindle (M70 or M0=70) or spindle with the number <n>
(M<n>=70) over to axis mode.
No defined position is approached. The NC block is enabled after the switchover
has been performed.
Motion end when "Exact stop fine" reached
Motion end when "Exact stop coarse" reached
End of motion on reaching "interpolator stop"
Spindle for which the programmed end-of-motion criterion is to be effective
Spindle number
<n>:
If a spindle is not specified in [S<n>] or a spindle number of "0" is specified, the
programmed end-of-motion criterion will be applied to the master spindle.
A block change is possible in the braking ramp.
Channel axis identifier
<axis>:
Instant in time of the block change with reference to the brak‐
<instant in
ing ramp
time>:
Unit:
Range of values:
If a value is not assigned to the <instant in time> parameter,
the current value of the setting data is applied:
SD43600 $SA_IPOBRAKE_BLOCK_EXCHANGE
Note:
IBOBRKA with an instant in time of "0" is identical to IPOEN‐
DA.
Synchronization command for the specified spindle(s)
The subsequent blocks are not processed until the specified spindle(s) program‐
med in a previous NC block with SPOSA has (have) reached its (their) end posi‐
tion(s) (with exact stop fine).
WAITS after M5:
WAITS after M3/M4:

ramp) to 0 (end of the braking ramp)
Wait for the specified spindle(s) to come to a standstill.
Wait for the specified spindle(s) to reach their setpoint
speed.
Numbers of the spindles to which the synchronization
command is to be applied.
If a spindle number is not specified or if the spindle
number is set to "0", WAITS will be applied to the
master spindle.
