6.3 Drive transducer interface
There are seven available transducers interfaces which can be used to convert actual values to be forwarded
to the controller:
• Analog input 0…4, used for pressure, position or other sensors
• Encoder
• SSI
• For special application any parameter can be mapped to an interface e.g. from a field bus.
The logic to select the interface is called transducer interface. The following figure shows how routing and
scaling of the actual value is done for the available inputs.
With the interface type <Type> (0x6202), the type of value conditioning can be selected depending on the
sensor.

Per default, analog input 0 and 1 are used for the analog setpoint values. Therefore the inputs
2…4 are normally used for actual values.

Before reading or writing configuration values of a particular transducer interface it is necessary to
select the particular interface by setting the interface number <InterfaceNumber> (0x6201).
