2 Introduction
This document describes the possibilities and the properties of the EM-RES-02 expan-
sion module for the frequency inverters of the ACT
and ACU device series.
Note: This document exclusively describes the EM-RES-02 expansion module. It
is not to be understood as fundamental information for the operation o
f
the frequency inverters of the ACT and ACU device series.
The EM-RES-02 expansion module is an optional hardware component to extend the
functionality of the frequency inverter. It enables the data exchange within the net-
work between the components which have been directly connected, for example con-
trol and regulation elements.
The EM-RES-02 expansion module is supported from device series ACU and as
from software version 4.1.0 of device series ACT.
The EM-RES-02 module extends the functionality of the frequency inverters of the
ACT
and ACU device series by the following additional functions:
− Analog input
(second bipolar analog input)
− Resolver input
− Repetition frequency output
Note: The EM-RES-02 expansion module has been enclosed with the frequency
inverter as a separate component and must be fitted by the user. This is
described in detail in the chapter "Mechanical Installation".
To assemble the expansion module it can be simply plugged into the frequency in-
verter of the ACT
and ACU device series.
Warning! The assembly is done before the frequency inverter is put into operation,
and only in a voltage-free state.
The pluggable sockets of the expansion module enable economical overall fitting with
a safe function.
