Parameters
Overview
The SED2 uses parameters to define the required operating
characteristics, such as motor data, ramp times, and maximum and
minimum frequency. Users enter and modify the SED2 parameters
using the Basic Operator Panel, the Advanced Operator Panel, or a
serial interface.
Each parameter consists of the letter "r" or "P", followed by four
numbers, such as r0000 or P0010. The letter "r" identifies read-only
parameters. The letter "P" identifies programmable parameters.
Parameter Structure
Figure 36 depicts the structure of the SED2 parameters.
• User Access Level parameter (P0003) selects the access level
for using the parameters (1=standard, 2=extended, or 3=expert).
The access level selected via parameter P0003 determines the
number of parameters that are accessible by the user. For most
applications, the Standard (1) and Extended (2) levels are
sufficient. The factory default setting is P0003=1 (Standard).
• The filters of Parameter Filter parameter (P0004) categorize the
parameters that are available via the access level according to
functionality. The filters/categories enable a more focused
operational approach. If parameter P0004=0 for no filter/category,
then all parameters for a selected user access level are available.
NOTE: Some parameters are intended for commissioning only
and can be viewed as a function of this filter. In order to
set these parameters, P0010 must be set to 1 (quick
commissioning).
