13.5.3 Logic gating functions: Source/reaction operation
Function
The static synchronized actions' flexible gating
possibilities are used to trigger specific reactions
according to the sources.
The operator has several options for gating all
relevant sources by means of static synchronized
actions. Users can evaluate the source system
variable as a whole or also selectively by means of
bitmasks and gate their desired reactions to them.
The static synchronized actions are effective in all
operating modes.
For a more detailed description on how to use
synchronized actions, please refer to

13.5.4 Activation
Enabling functions:
$AA_ESR_ENABLE
The generator operation, stop and retract functions
are enabled by setting the associated control signal
($AA_ESR_ENABLE). This control signal can be
modified by the synchronized actions.
Triggering functions (general triggering of all
released axes)
$AN_ESR_TRIGGER
•
Generator operation is "automatically" active in
the drive when a pending DC link undervoltage is
detected.
•
Drive-independent stop and/or retract are active
when a communications failure (between the NC
and drive) is detected, as well as when a DC link
undervoltage is detected in the drive (providing it
is configured and enabled).
