5 Frequency inverters - settings and control elements
5.1 Frequency inverter bus parameters
To operate the inverter with the DeviceNet protocol, the bus must be connected to the Master and some
settings must be made on the frequency inverter.
With the DeviceNet protocol, the inverter parameters are mapped onto DeviceNet objects in the range 100 to 109:
- Class = 100 + parameter number / 100
- attribute = parameter number % 100
- instance = sub-index +1 or - Parameter number = (class – 100) * 100 + attribute
- sub-index = instance -1
The frequency inverter can always be parameterised. Control of the inverter via DeviceNet can be activated by
setting parameter P509 to value 18, 19 or 20 (SK 500E: value 7). (see below)

Function Bus I/O In Bits
The Bus I/O In Bits are perceived as digital inputs. They can be set to the same functions as the digital
inputs (See P420…of the respective FI manual). 0 ... 72
