Retract (drive-independent)
Drive-independent retract
is
• configured: via MD; time specification and return
velocity are set in MD, see "Example: Using the
drive-independent reaction" at the end of this
chapter,
• enabled: system variable $AA_ESR_ENABLE
• triggered: system variable $AN_ESR_TRIGGER.
13.5.2 Possible trigger sources
Function
The following error sources for starting "Extended
stop and retract" are possible:
•
General sources (NC-external/global or mode
group/channel-specific):
•
Digtial inputs (e.g. on NCU modules or
terminal blocks) or mapping the digital
outputs within the control ($A_IN, $A_OUT)
•
Channel status ($AC_STAT)
•
VDI signals ($A_DBB)
•
Group messages from a number of
alarms ($AC_ALARM_STAT)
•
Axial sources:
•
Emergency retraction threshold of the
following axis (synchronization of
electronic coupling,
$VA_EG_SYNCDIFF[following axis])
•
Drive: DC link warning threshold (pending
undervoltage), $AA_ESR_STAT[axis]
•
Drive: Generator minimum velocity
threshold (no more regenerative rotation
energy available), $AA_ESR_STAT[axis].
