Chapter 16 Expansion model
2 and 3 port Corrigo units are available with or without display. Both models have a TCP/IP port
and one or two serial ports. For a list of the various models, see the Corrigo model overview in
chapter 2.
16.1 Ports
The ports are used for connecting to E tool

and, possibly, a SCADA system. In an E…3W-3
model, port 3 is the TCP/IP output.
The serial ports (ports 1 and 2) are used for expansion purposes, e.g for connection of expansion
units, external display and Vacon NXL/Lenze SMV/Omron/Emerson/LS/EBM/Danfoss FC 101
frequency converters. A maximum of two frequency converters and two expansion units can be
connected. The units must be Corrigo controllers. There is no point in using slave controllers with a
display, since the display cannot be used or show anything. However, an E3-DSP is required when
initially starting up slave units without display. All configuration takes place using E tool

, or via
the display on the master controller. All inputs and outputs can be viewed in the master controller.
For configuration, see chapter 17.
As of version 3.1, frequency converters and expansion units can be used together.
Ports 1 and 2 have the same functions. They can, however, not be configured to have the same
function at the same time. The TCP/IP port (port 3) can be used to connect the controller to
CLOUDigo or, optionally, to load a web page to the unit. For more information, see the E tool

manual.
16.2 Wiring
16.2.1 Vacon/Lenze/Omron/Emerson/LS/EBM frequency
converters
If the Corrigo is intended to control of one or two of the Vacon NXL/Lenze SMV/Omron
V1000/Emerson frequency converters, Modbus communication via port two is utilised.
For additional settings for frequency converters, see appendix at the end of this document.
