6.1 Introduction to the SED2 system parameters

6.1.1

General notes

You can change the parameters only via the basic operator panel (BOP), the
advanced operator panel (AOP), or the serial interface.
The BOP or AOP can be used to enter and change parameters to define the required
characteristics of the variable speed drive, such as motor data, ramp times, maximum
and minimum frequency, etc.
Read-only parameters are identified by the letter "r" in place of the "P".
Ø
P0010 = 1 initiates the "Quick commissioning" procedure.
Ø
The variable speed drive runs only if P0010 is set to 0 after access. This function is
Ø
automatic if P3900 is greater than 0.
P0004 operates as a filter and allows access to the parameters according to their
Ø
functionality.
If you attempt to change a parameter that cannot be changed under the current
Ø
conditions (e.g., because it cannot be changed during operation or can only be
changed in the "quick commissioning" mode),
Busy signal
Ø
In some cases, the BOP displays
parameters are being changed. This means that the variable speed drive is busy
with higher-priority activities.

6.2 Access to parameters

6.2.1

Parameter access levels (P0003)

In total, there are four access levels. The three access levels available to the user are
Standard, Extended, and Expert. Set the required access level with parameter P0003.
For most applications, the Standard and Extended levels are sufficient.
The number of parameters displayed within each function group depends on the
access level set in parameter P0003. The factory setting is P0003 = 1 (Standard).
Refer to the engineering manual for detailed information about the parameters.
6.2.2

Parameter filter (P004)

You can further limit the selection of available parameters with parameter filter P0004.
This filters the available parameters by their functionality. For example, if P0004 = 3,
only the motor parameters are visible.
Some parameters are intended for commissioning only and can be viewed as a
function of this filter. However, in order to set these parameters, set P0010 to 1 (quick
commissioning).
