Manual for 362MC Nr. 9360000120 Edition: 2/00 Subject to modifications
Example
The functions of the setpoint programme are illustrated below by reference to a possible application for
the 362MC functional extension Setpoint programme in conjunction with changeover to a 2
nd
setpoint.
In this example, the speed of a motor is to be selectable in two speed ranges, fast and slow , via a
changeover selector. The transitions between the speeds, slow>fast and fast>slow , are to be effected
gently and in several steps during changeover.
To this end, the parameter 2Setp has been assigned to input E5 in the Input menu and a slow
changeover contact of the changeover selector has been connected to this binary input. The value
range has been selected in the Input menu as Scale-0=0, Scale-F=100 and Dim=% . In the Setpoint
menu , the value StpPrg1 (slow>fast) has been assigned to parameter 1SpTypA and the value StpPrg2
(fast>slow) has been assigned to 1SpTypB . The two setpoint programmes are defined as shown in the
following tables. The resultant functional sequence is shown in the diagram.

Parameterisation of display function
If one setpoint type SpTyp is set to a StpPrg ( 1 to 5 ) the display function for setpoint programmes are
selectable in the extended Display menu (5.8) . The extended display menu are shown in the following
table.
