Danfoss VLT series Programming Guide

Enable Input. Therefore, the general rules for the Enable
input do not apply here. This function block is implicitly
enabled. The Enable input of this function block controls
the DC-link voltage on the output lines of the SAB. All
outputs are always updated (so Valid can be TRUE, even if
Enable is FALSE).
The input TimeLimit represents the maximal duration of
functionality. If the TimeLimit is exceeded during switching
on the SAB, an Error is signaled at the outputs. However,
the functionality according to the Enable input is
continued. If Enable is TRUE, the function block continues
to attempt to enable the DC-link voltage of the SAB. If
Enable is FALSE, the function block continues to attempt to
disable the DC-link voltage of the SAB. If the SAB starts
reacting again, the Error output can change to FALSE again
without a new rising edge of Enable. Set the value to 0 to
disable the time limit functionality.
The command is transferred immediately, but it can take
some time until the SAB has enabled the DC-link voltage
and the output Status becomes TRUE.
6.5.8.3 DD_Reset_SAB
This function block makes the transition from the state
Fault to Standby by resetting all internal SAB-related errors.
It does not aect the output of the function block
instances.
The command is transferred and executed immediately.
