2 Introduction
This document describes the possibilities and the properties of the EM-SYS expansion
module for the frequency inverters of the ACT and ACU series of devices.
Note: This document exclusively describes the EM-SYS expansion module. It
does not provide basic information on the operation of the ACT and
ACU series frequency inverters.
The EM-SYS expansion module is an optional hardware component to extend the
functionality of the frequency inverter. It enables the data exchange within the net-
work and between the components, which have been directly connected, for example
control and regulation elements.
The EM-SYS expansion module is supported from device series ACU and as from
software version 4.1.0 of device series ACT.
The EM-SYS module extends the functionality of the frequency inverters of the ACT
and ACU series of devices by the following additional functions:
− CAN system bus
(CAN interface ISO-DIS 11898, CAN High Speed, max. 1 MBaud)
Note: The EM-SYS 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-
verters of the ACT and ACU device series.
Warning! Carry out the assembly before the frequency inverter is put into opera-
tion, and only in a voltage-free state.
The pluggable sockets of the expansion module enable economical overall fitting with
a safe function.
