SINUMERIK 840D/810D Operator's Guide ManualTurn (BAM) – 08.02 Edition
Spindle does not stop on block change
The displayed spindle has been programmed as a spindle or an axis
although a positioning operation from a previous block is still running
(with SPOSA ... spindle positioning beyond end of block).
Example
N100 SPOSA [2] = 100
.
.
N125 S2 = 1000 M2 = 04
NC start disable
NC stop on alarm
Alarm display
Interface signals are set
Before reprogramming the spindle/axis after a SPOSA instruction,
trigger a wait for the programmed spindle position with the WAITS
command.
Example
N100 SPOSA [2] = 100
.
.
N125 WAITS (2)
N126 S2 = 1000 M2 = 04
Reset alarm with RESET key. Restart program.
Reference mark not found
On referencing, the spindle rotated further than specified in axis-
specific MD 34 060 REFP_MAX_MARKER_DIST without receiving a
reference mark signal. This is checked on spindle positioning with
SPOS or SPOSA if the spindle has not yet turned with speed control
(S=...).
NC start disable
NC stop on alarm
Alarm display
Interface signals are set
Check and correct MD 34 060 REFP_MAX_MARKER_DIST. The
value entered specifies the path in [mm] or [degrees] between 2 zero
marks.
Reset alarm with RESET key. Restart program.
No transition from speed control to position control
• A spindle stop (SPOS/SPOSA) has been programmed or the
position control of the spindle has been activated with SPCON but
no spindle encoder is defined.
• When the position control is activated the spindle speed is greater
than the limit speed of the measuring system.
