7.4 Positioning spindles (SPOS, M19 and SPOSA, WAITS)
Function
With SPOS, M19 and SPOSA, you can position spindles at specific angular positions, e.g.,
during tool change. In order to synchronize spindle movements, WAITS can be used to wait
until the spindle position is reached.
The spindle can also be operated as a path axis, synchronized axis or positioning axis at the
address defined in the machine data. When the axis identifier is specified, the spindle is in
axis mode. M70 switches the spindle directly to axis mode.
Switching off
SPOS, M19 and SPOSA effect a temporary switchover to position-controlled operation until
the next M3 or M4 or M5 or M41 to M45. If the position control was activated with SPCON
prior to SPOS, then this remains active until SPCOF is issued.
