Differences Between The Old Μline And The New Cfw-08 - WEG CFW08 Vector inverter User Manual

2.3.1 Differences between the
old µ line and
the new CFW-08
This section aims at showing the differences between the old µline and
the new CFW-08. The information below are addressed to user that are
used to µline.
Table below shows the equivalence between the accessories of the old
µline an the new CFW-08.

Product Appearance
Besides the internal electronics, also the exterrnal product appearance
have changed, which are:
the frontal lettering on the plastic covers (formerly: µline, now:
-
CFW-08 vector inverter);
- WEG logo is now indicated on all accessories of the CFW-08 line
(keypad, communication modules etc).
Figure below makes a comparison:

Version of Software
The new CFW-08 starts with Software Version V3.00. Thus, the software
Versions V1.xx and V2.xx are exclusive for µline.
Besides the inverter control has been implemented in a DSP (Digital
Signal Processor), which enables a more sophisticated control with
more parameters and functions.
Accessories
With the migration from the 16 bits microcontroller to the DSP of the
new CFW-08, the power supply of the electronic circuits had to be
changed from 5V to 3.3V. Consequently, the accesories (keypads,
communication modules, etc) of the old µline CAN NOT BE USED
with the new CFW-08 line. As general rule, use only accessories with
WEG logo, as already informed above.
