The program advances to the next block if the end of motion criteria for the spindle or axes programmed in the current block
plus the block change criterion for path interpolation are fulfilled.
Synchronization
In order to synchronize spindle movements, WAITS can be used to wait until the spindle position is reached.
Conditions
The spindle to be positioned must be capable of operation in position-controlled mode.
Programming
Position spindle:
SPOS=<value>
SPOSA=<value>
M19/M<n>=19
Switch spindle over to axis mode:
M70/M<n>=70
Define end-of-motion criterion:
FINEA/FINEA[S<n>]
COARSEA/COARSEA[S<n>]
IPOENDA/IPOENDA[S<n>]
IPOBRKA/IPOBRKA(<axis>[,<instant in time>]) ; Programming in a separate NC block.
Synchronize spindle movements:
WAITS/WAITS(<n>,<m>) ; Programming in a separate NC block.
Significance
SPOS
/SPOSA: Set spindle to specified angle
SPOS and SPOSA have the same functionality but differ in their block change behavior:
•
SPOS delays the enabling of the NC block until the position has been reached.
•
SPOSA
enables the NC block even if the position has not been reached.
<value>: Angular position to which the spindle is to be set.
Unit: degrees
Type: REAL
The following options are available about programming the position approach mode:
=AC(<value>): Absolute dimensions
Range of values: 0 … 359,9999
=IC(<value>): Incremental dimensions
Range of values: 0 … ±99 999,999
=DC(<value>): Approach absolute value directly
=ACN(<value>): Absolute dimension, approach in negative direction
=ACP(<value>): Absolute dimension, approach in positive direction
=<value>: as DC(<value>)
M<n>=19
: Set the spindle (M19 or M0=19) or spindle 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.
M<n>=70
: Switch the spindle (M70 or M0=70) or spindle 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.
FINEA:
Motion end when "Exact stop fine" reached
COARSEA:
Motion end when "Exact stop coarse" reached
