Syntax
Position spindle:
SPOS=<value> / SPOS[<n>]=<value>
SPOSA=<value> / SPOSA[<n>]=<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.
Meaning
SPOS / SPOSA:
118
Set spindle to specified angle
SPOS and SPOSA have the same functionality but differ in their block change
behavior:
● With SPOS, the NC block is only enabled once the position has been reached.
● With SPOSA, the block is enabled even if the position has not been reached.
Number of the spindle to be positioned.
<n>:
If a spindle number is not specified or if the spindle number is set
to "0", SPOS or SPOSA will be applied to the master spindle.
Angular position to which the spindle is to be set.
<value>:
Unit:
Type:
