The SK CU4 - POT potentiometer adapter is an exception among the "SK CU4 Modules", since it is not
integrated in the device but attached to it.
Communication between "intelligent" option modules and the device takes place via the system bus.
Intelligent option modules are modules with their own processor and communication technology, as is
the case with field bus modules, for example.
The frequency inverter can manage the following options via its system bus:
1 x ParameterBox SK PAR-3H and (via an RJ12 connector)
1 x field bus option (e.g. Profibus DP), internal or external and
2 x I/O extension (SK xU4-IOE-…), internal and / or external
Up to 4 frequency inverters with their appropriate options can be connected to a system bus.
