6.5.8 SAB

6.5.8.1 SAB_REF

Represents the state of an ISD 510 Servo Access Box. It
handles the PDO communication and the internal state. To
use the SAB-related function blocks, instantiate 1 function
block for each SAB used. Also, connect the inputs and
outputs to the objects that are mapped in the
development environment for synchronous communication

6.5.8.2 DD_Power_SAB

Controls the power for the output lines (On or Off). The
Enable input enables the DC-link voltage on the output
lines and not the function block itself.

Table 6.71 DD_Power_SAB
If the DD_Power_SAB function block is called when Enable
= TRUE while in Standby state, the SAB state changes to
Operation enabled.
The error variable is set to TRUE if the Enable input is TRUE
for the time specified in the input TimeLimit, while the
Status remains FALSE. It indicates a hardware problem with
the power stage. If power fails, also during operation, it
generates a transition to the Fault state.
Only issue 1 function block DD_Power_SAB per SAB.

Description
Reference to the SAB.
See chapter 6.5.8.1 SAB_REF.
If this input is true, DC-link
voltage for the lines is enabled.
Timeout after which an error is
signaled if the Status has not
changed to TRUE while Enable
is TRUE. Set the value to 0 to
disable the time limit.
Effective state of the DC-link
voltage on the output lines.
If TRUE, the function block has
a valid set of outputs.
An error has occurred within
the function block.
