EM-RES-03 710/07
2 Introduction
This document describes the possibilities and the properties of the EM-RES-03 expan-
sion module for the frequency inverters of the ACU device series.
Note: This document exclusively describes the EM-RES-03 expansion module. I
is not to be understood as fundamental information for the operation o
the frequency inverters of the ACU device series.
Note: The expansion module EM-RES-03 can be used only with frequency in-
verters of the ACU series. It is not applicable for frequency inverters o
f
the ACT series.
The EM-RES-03 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-03 module extends the functionality of the frequency inverters of the
ACU device series by the following additional functions:
− CAN system bus
(CAN interface ISO-DIS 11898; CAN High Speed; max. 1 MBaud)
− Analog input
(second bipolar analog input)
− Resolver input including PTC evaluation via SubD-9 connection
− Three digital inputs
− Two digital outputs
− Voltage output DC 24V
Note: The EM-RES-03 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 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 fittin
with
a safe function.
Note: The EM-RES-03 expansion module differs in the resolver evaluation from
the expansion modules EM-RES-01 and EM-RES-02. The frequency of the
excitation signal is set to the fixed value 8 Hz. This module is applicable
for BONFIGLIOLI motor types BCR and BTD.
