ATV61
conguration
principle
5 data is periodically read from ATV61 and stored in PLC from %MW900.
Considering the ATV61, the input and output I/O scanning parameters can be congured in different ways:
using Power Suite software v
using the ATV_61 graphic display terminal v
using the ATV_61 Web server and Internet Explorer v
In Power Suite a dedicated screen is used to declare the data exchange with PLC. A rst parameter is added for
status purpose. These parameters are numbered from 0.
In UNITY PLC conguration the number of parameters declared in the drive will determine the length of
registers to Read and to Write with the I/O scanner.
The rst parameter is reserved
Length=4 words (parameters congured) +1 reserved=5words

PLC and motor control device conguration
The following example presents a conguration of four input variables in Power Suite (Variable speed drive
conguration) and in Unity I/O scanning service (PLC software)
Similar work is necessary for output variables.
