The Inverter contains a number of settings
which can be changed to tailor it for use with a
wide range of motor ratings and applications.
These settings are known as parameters.
Parameters are typically referred to by code or
number (eg. P401 = Rated Motor Current) with
a description available in the manual.
The parameters contain critical information
essential to the correct operation of the
Inverter. Therefore, they should at least be
checked by the installer before the Inverter is
operated for the first time.
The parameters listed in section 5 are intended
to provide a starting point to allow for basic
operation of the CFW-08 Inverter.
5. Parameters to set before use
See section 6 to learn how to set a parameter value.
Set the following parameters to allow the
CFW-08 to control a motor with Run, Stop and
Speed Control from the keypad.
If any of the parameters have been changed
previously, follow the procedure in section 15
to reset the Inverter to Factory Defaults.
5.1 Parameters to check and values to set
WEG CFW-08 Series Inverter
Note: Although some parameters are only used in Sensorless Vector Mode (see Section 9), we recommend that all the above are set.
