ABB PST72 Installation And Maintenance Manual

Tuning parameters
Six parameters can be tuned individually if a more specic adjustment is required. Each
parameter is described in Chapter 10 “ Functions” .
•
Start ramp
• Stop ramp
• Initial voltage
• End voltage
• Step down voltage
• Current limit level
When all tuning parameters have been cycled through, the following information will be
displayed, Figure 21. Select Yes if all necessary parameters are tuned. If a new tuning is
required, select Back and follow the step Tune Set above
7:2.3 Basic Settings
The Basic settings menu consists of the most common start/stop parameters required for
the set-up. Each parameter can be adjusted separately. For a detailed description of each
parameter, see Chapter 10 “ Functions” .
Enter the Basic settings
Enter the menu by selecting
Basic Settings.
Setting I
e
(motor FLA)
Set the current that the softstarter will be exposed to (i.e. rated motor current, if the unit is
connected In Line).
Information!
For units connected Inside Delta the Setting I
e
must be set according to the current in the
delta circuit = 58% (1/( 3)) of the rated motor current. Press Store to save the data after
setting the current
External By-Pass contactor (Ext ByPass)
Set the parameter to Yes if an External By-pass Contactor is used, otherwise select No.
Start ramp
Set the ramp time for start.
Stop ramp
Set the ramp time for stop (softstop). Note that this function should only be used for
applications with small ywheel masses, for example pumps and conveyors (minimizes
product damage during the stop).
Initial voltage (Init Volt)
Set the initial voltage level.
End voltage (End Volt)
Set the end voltage level.
Step down
Set the level of the step down voltage. This function is only present if softstop is selected.
Current limit (Current Lim)
Set the current limit level for the start.
Overload Class (OL Class)
Select the desired overload class.
The conguration of the basic setting menu is now completed. It is possible to return to
the top level by pressing Back 3 times.
