In some cases - when changing parameter values - the display on the BOP shows
There are four levels of user access, Standard, Extended, Expert and Service selectable
by parameter P0003. For most applications, Standard and Extended parameters are
The number of parameters that appear within each functional group depends on the
access level set in parameter P0003. This document describes access levels 1 and 2
(standard and extended) other settings are described in the Reference Manual.
Quick commissioning (P0010=1)
It is important that parameter P0010 is used for commissioning and P0003 is used to
select the number of parameters to be accessed. This parameter allows a group of
parameters to be selected that will enable quick commissioning. Parameters such as
Motor settings and Ramp settings are included.
At the end of the quick commissioning sequence, P3900 should be selected, which, when
set to 1, will carry out the necessary motor calculations and clear all other parameters
(not included in P0010=1) to the default settings. This will only happen in the Quick
Reset to Factory default
To reset all parameters to the factory default settings; the following parameters should be
set as follows:
The reset process takes approximately 10 seconds to complete.
for maximum of five seconds. This means the inverter is busy with tasks of
