Connection example for Active Interface Module
The Active Interface Module requires a 24 V DC supply for
operation of the integral fan.
The fan rotates after the 24 V DC supply is applied and can, if
necessary (service life, noise), be disconnected from the Control
Unit over the "Fan off" input. It is only permitted to switch off the
fan when the infeed of the drive system is not operating, other-
wise the Active Interface Module will overheat.
The thermostatic switch installed in the Active Interface Module
is evaluated over the connected Active Line Module.
The power cables between the Active Interface Module and
Active Line Module must be shielded if limit values for inter-
ference suppression are to be complied with. The cable shield
can be routed over the shield connection plate (option) to the
Active Interface Module or Active Line Module.
Depending on the position of the Active Interface Module in the
drive system, additional DRIVE-CLiQ cables may be required.
If it is separately installed next to the left side of the Control Unit
and Active Line Module, no additional DRIVE-CLiQ cables are
required. If the Active Interface Module is placed between the
Control Unit and Active Line Module, the DRIVE-CLiQ cables
supplied with the Active Line Modules are suitable for setting up
a line topology, i.e. Active Line Module and all Motor Modules
in series on one DRIVE-CLiQ line. If the Active Line Module is
connected over a separate DRIVE-CLiQ line, the DRIVE-CLiQ
cable marked with (1) must be ordered. A DRIVE-CLiQ cable
suitable for connection (2) is included in the scope of supply
of the Active Line Module.
For DRIVE-CLiQ cables for different configurations,
see section MOTION-CONNECT connection systems.
