Physical units 

For trouble-free operation, the units of the process data transmitted on the field bus have to be defined. 

They can be set in the menu 

Physical units Profibus

 called by  

Parameters/Fieldbus/Profibus

. 

The 

parameters of the physical units should be set once and then remain unchanged during a 

running application. 

 

Unit-related factors are calculated internally so that all the user has to do is to select the desired unit. 

The gear ratio and the feed constant are stated as separate parameters.  

Figure 7.1 shows the physical unit set-up menu of the DIS-2 ServoCommander

TM

 program. 

 

Figure 7.1:

 Setting of physical units

 

When the physical units are entered, the firmware automatically calculates conversion factors. They 

consist of a numerator and a denominator which can comprise a maximum of 32 bits each. If an 

overflow occurs when the factors are entered, the value will be rejected. In this case, the factors or the 

physical units have to be corrected. 

It has to be taken into consideration that some quantities cannot always be used in a sensible manner. 

A purely rotative system, for example, does not require a feed constant. Apart from this, the feed 

constant has a physical unit. If this unit is not parameterized correctly, the feed constant will be 

ignored.
