SINUMERIK 840D/840Di/810D/FM-NC Programming Guide Advanced (PGA) – 04.00 Edition
As an independent drive mode, it provides the
drive DC link with the necessary power to
perform an orderly "stop" and "retract" in the
event of a power failure or similar occurrence.
All reactions can be used independently from one
another.

13.5.1 Drive-independent reactions
Function
Drive-independent reactions are defined axially; if
activated, each drive processes its stop/retract
request independently. There is no interpolatory
coupling of axes or coupling adhering to the path at
stop/retract, the reference to the axes is time-
controlled.
During and after execution of drive-independent
reactions, the respective drive no longer follows the
NC enables or NC travel commands. Power
OFF/Power ON is necessary. Alarm "26110: Drive-
independent stop/retract triggered" draws attention
to this.
Generator operation
Generator operation is
•
Configured: via MD
•
Enabled: system variable $AA_ESR_ENABLE
•
Activated: depending on the setting of the drive
machine data when the voltage in the DC link
falls below the value.
Stop (independent drive)
Drive-independent stop is
•
Configured: via MD as well as time specification
via MD;
•
Enabled ($AA_ESR_ENABLE) and
•
Triggered: system variable $AN_ESR_TRIGGER.
