ABOUT THE CTW900

4.1

MANUAL INFORMATION

This manual presents the information necessary for the configuration of all the functions and parameters of the
CTW900.

Due to the wide range of functions of this product, it may be used in applications different from those presented
hereby.  Neither  does  this  manual  aim  at  presenting  all  the  possible  applications  of  the  CTW900,  nor  can  the
manufacturer take any liability for the use of the converter which is not based on this manual.

In  order  to  obtain  more  detailed  information  on  the  SoftPLC  function  or  the  expansion  and  communication
accessories, refer to the following manuals:

■

Manual of the SoftPLC;

■

Manual of the interface modules for Incremental Encoder;

■

Manual of the I/O expansion modules;

■

Manual of the Modbus RTU communication;

■

Manual of the Anybus-CC communication.

Those manuals are supplied in electronic file in the CD-ROM that comes with the product, or can be
downloaded at WEG website – www.weg.net.

4.2

SOFTWARE VERSION

The software version used on the CTW900 is important, since it defines the functions and programming
parameters.

This manual refers to the software version as indicated on the back cover. For instance, the version 1.0X means
from 1.00 to 1.09, where “X” are the evolutions in the software that do not affect the content of this manual.

You can check the software version in parameter P0023.

CHARACTERISTICS

The AC/DC Converter

CTW900

is a high performance product intended to drive and control DC motors with

independent excitation for speed variation and control in one or four quadrants of the Torque x Speed curve.

Figure 4.1

– Torque x Speed curve for a mechanical drive

Among its main characteristics, we may point out:

■

Keypad with 2.5” LCD which allows viewing different kinds of information simultaneously;

■

USB for serial communication and firmware update;

■

Memory card for backup of parameters and software applications;

■

Log of the ten last faults;

■

SoftPLC function to create specific programs;
