5.3.1 Description of the basic operator panel (BOP)
The basic operator panel (BOP) provides access to the parameters of the VSD and
allows for application-specific settings of the SED2.
The parameters and measured values are shown in a 5-digit LCD display. The basic
operator panel can be mounted directly onto the variable speed drive or, alternatively, it
can be mounted into a control cabinet door using a special installation kit.
You cannot store parameter information with the basic operator panel.
For information on setting and changing parameters, refer to section 5.4.4.2 Setting
parameters with the BOP or AOP.
