Spindle Functions After Block Search - Siemens SINUMERIK 840D sl Function Manual

K1: Mode group, channel, program operation, reset response
9.7 Block search, types 1, 2, and 4:
When the alarm is displayed can be set via machine data:
MD11450 $MN_SEARCH_RUN_MODE, Bit 0 = <value>
<value> Meaning
In combination with the alarm, the following interface signals are set:
● DB21, ... DBX36.7 = 1 (NC alarm with machining standstill is pending)
● DB21, ... DBX36.6 = 1 (NC alarm channel-specific is pending)
9.7.2.3

Spindle functions after block search

Control system response and output
Whether the spindle-specific auxiliary functions collected during block search are automatically
output to the PLC in the action block or user-specifically at a later time can be set in
MD11450 $MN_SEARCH_RUN_MODE, Bit 2 = <value>
<value> Meaning
System variables
The spindle-specific auxiliary functions collected during block search are stored in the following
system variables:
System variable
$P_SEARCH_S [ <n> ]
$P_SEARCH_SDIR [ <n> ]
$P_SEARCH_SGEAR [ <n> ]
$P_SEARCH_SMODE [ <n> ]
$P_SEARCH_SPOS [ <n> ]
484
0 With the change of the last action block after a block search, the following takes place:
● Execution of the part program is stopped
● DB21, ... DBB32.6 = 1 (last action block active)
● Display alarm 10208
1 With the change of the last action block after a block search, the following takes place:
● Execution of the part program is stopped
● DB21, ... DBB32.6 = 1 (last action block active)
● Only display alarm 10208 if DB21, ... DBX1.6 == 1 (PLC action ended)
0 Output of spindle-specific auxiliary functions collected during block search (M3, M4, M5, M19,
M70) in action blocks.
1 The spindle-specific auxiliary functions collected during block search are not output in the
action block.
They can be output at a later time, for example, in an ASUP. The spindle-specific auxiliary
functions collected are stored in system variables:
Description
The spindle speed or cutting speed last programmed
Spindle direction last programmed
Gear stages last programmed M function
Spindle mode last programmed
Spindle position or traverse path last programmed by means of
M19, SPOS or SPOSA
