Internal process data mapping with data format "Standard". Depending on the fieldbus specification
and the data format of the communicating fieldbus components the bytes and/or the words can be
reversed during the data transfer. For byte/word order for each network adapter refer to Section, Data

5.21 Digital Pulse Width Modulation Output Module
EP-5422

Modulation Output Module
EP-5422
Figure 154: Connection Diagram EP-5422
The digital pulse width modulation module EP-5422 is used for the control of small motors
with current requirements of up to 0.5 A. The period duration for each channel can be
parameterized from 25
μ
s to approx. 175ms (input values from 1,202 to 8,388,607 based
on a factor 0.02083
μ
s).
Via an output double word in the process data the pulse duration is defined from 0
μ
s to
approx. 175ms for each channel (input values from 0 to 8,388,607 based on a factor
0.02083
μ
s). If the pulse duration is equal or exceeds the duration of the period, the output
is set permanently.
