Axial sources
• Emergency retraction threshold of the following axis (synchronization of electronic
coupling, $VC_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].
Gating logic for the static synchronized actions: Source/reaction logic operation
The static synchronized actions' flexible gating possibilities are used to trigger specific
reactions relatively quickly according to the sources.
The operator has several options for gating all relevant sources by means of static
synchronized actions. They can selectively evaluate the source system variables as a whole
or by means of bit masks, and then make a logic operation with their desired reactions. The
static synchronous actions are effective in all operating modes.
For a detailed description of how to use synchronized actions, please see:

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.
Function initiation (general triggering of all released axes)
$AN_ESR_TRIGGER
Generator operation "automatically" becomes active in the drive when the risk of DC link
undervoltage is detected.
Drive-independent stop and/or retract are activated when communication failure is detected
(between NC and drive) as well as when DC link undervoltage is detected in the drive
(providing they are configured and enabled).
Drive-independent stop and/or retract can also be triggered from the NC side by setting the
corresponding control signal $AN_ESR_TRIGGER (broadcast command to all drives).
