Chapter 6 — Programming

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.

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).
