13.1.2 Determination of the maximum cable length AGG5.6
The maximum cable length between transformer and CAN bus users depends on the
type of cable (cross-sectional area), the number of actuators, and the type of actuator
(current).
The following graphs can be used to determine the maximum CAN bus cable lengths
between the transformer and the group of actuators or the AZL5, depending on the
relevant influencing factors.
The assumption was made that the actuators within the group are close to one another.
The minimum cross-sectional area for the system examples shown results from the
start of the curve.
The maximum cable lengths for the defined system cables AGG5.641 and AGG5.631
result from the points of intersection in the graph.
