Power Off/Power On; Operating Mode Change, Nc Stop, Reset - Siemens SINUMERIK 840D sl Function Manual

R3: Extended stop and retract
9.2 Control-managed ESR - 840D sl only
Initial situation
● $AA_ESR_ ENABLE[X] = 1
● $AA_ESR_ ENABLE[B] = 0
● POLFMASK(X)
● Program traversing motion: X and B
● $AA_ESR_ ENABLE[X] = 1
● $AA_ESR_ ENABLE[B] = 1
● POLFMASK(X)
● Program traversing motion: X and B

POWER OFF/POWER ON

If the user-specific retraction logic is programmed within motion synchronized actions, then it
must be observed that this is still not active when the control boots (POWER ON). A retraction
logic, which should be active after POWER ON, must therefore lie in an ASUB started from
the PLC or must be called event-controlled.

Operating mode change, NC Stop, reset

Static synchronized actions (IDS keyword) can be used for user-specific retraction logic as the
following system states or state change have no influence on this:
● Operating mode change, e.g. DB11 DBX0.0 (AUTOMATIC)
● NC stop, e.g. DB21, ... DBX7.3 (NC stop)
● Reset, e.g. DB21, ... DBX7.7 (reset)
Note
NC stop and command axes
Traversing command axes is interrupted for an NC stop.
Note
POLF/POLFMASK reset and program commands
For reset, the programmed absolute retraction positions (POLF) and the enable signals for the
retraction axes (POLFMASK) are not deleted.

Response in the case of ESR
B is not enabled for ESR. As B is not a path axis, B is immediately stopped
with a rapid stop.
X executes retraction motion.
B is not enabled for retraction (POLFMASK). However, as B is enabled for
ESR, for B, the ESR response is implicitly changed to 22 (stopping). This is
the reason that B continues to traverse corresponding to the programmed
traversing motion.
Y executes retraction motion.
After the delay time for ESR axes expires, MD21380, $MC_ESR_DE‐
LAY_TIME1, B is stopped with axial acceleration.
