Using the Parameters
• Modify SED2 parameters using the BOP, the AOP, or the serial interface. Use the
BOP or AOP to enter and modify parameters that define the required characteristics
of the SED2, such as motor data, ramp times, and maximum and minimum
frequency.
• Read-only parameters are identified by the letter “r”, programmable parameters are
identified by the letter “P”.
• Commissioning Parameter Filter P0010=1 initiates the Quick Commissioning
procedure.
• The SED2 runs only if P0010 is set to 0 (factory setting) after access. This function is
automatic if P3900 is greater than 0.
• P0004 operates as a filter and allows access to the parameters according to their
functionality.
• If you attempt to modify a parameter that cannot be modified under the current
conditions (such as, because it cannot be modified during operation or can only be
modified in the Quick Commissioning mode), the display reads
.
• Busy Signal — While changing parameters, the BOP can display
for a
maximum of 5 seconds. This display means that the SED2 is busy with higher-priority
activities.
SED2 Parameter Structure
Figures 23 and 24 shows 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 number of parameters
accessible depends on the access level selected via parameter P0003. For most
applications, the Standard and Extended levels are sufficient. The factory setting of
P0003 is set to 1 (Standard).
• The filters of Parameter Filter 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 is set to 0 for no filter/category,
then all parameters for a selected user access level are available.
