Process Data Structure

Figure 5.2

Different shaft position for multiturn versions depending on singleturn resolutions

The example also shows that the current shaft position (= MDC1 - Position) and the set sin-
gleturn resolution (= Config - ST Resolution = MDC1 - ST Resolution) can be used to determine
the corresponding multiturn position (= number of full revolutions completed). If a complete rev-
olution means 1000 steps, a measured value equating to MDC1 - Position = 1875 means that
one full revolution and a further 875 steps of the next revolution have been completed.

Refer to information on the "MDC1 - ST Resolution" process data content and the "Config -
Position Overflow" parameter.

5.2

MDC1 - Position

Measurement Data Channel 1 - Position

The "MDC1 - Position" process data content returns the current absolute shaft position. If the
shaft is rotated when the device is disconnected from the power supply, the new shaft position
is updated and immediately available once the device is switched on again.

The number of measuring steps that are counted in one revolution can be set as required.

Refer to information on the "Config - ST Resolution" and "Position Value - Overflow" parame-
ters.

5.3

MDC1 - ST Resolution

Measurement Data Channel 1 - Singleturn Resolution

The "MDC1 - ST Resolution" process data content describes the singleturn resolution and cor-
responds to the value set as the "Config - ST Resolution" parameter.

This value determines how many measuring steps are counted in

one

full revolution.

Refer to information on the "Config - ST Resolution" parameter.

The cyclical transmission of the set singleturn resolution offers significant added value in condi-
tion monitoring applications. The position value from the "MDC1 - Position" process data can
be more easily interpreted.

The "MDC1 - ST Resolution" process data can be used to calculate the current multiturn posi-
tion at any time for all multiturn versions.

The following figure illustrates this with an example for singleturn-only device versions.
