3.1 Operating modes
It is differentiated between the absolute position, differential value and Modulo operating
modes.

Table 2: Display with different operating modes
Absolute position:
Linear absolute position values are displayed.
Differential value display:
With factory setting: Differential value = actual position - set point
(for calculating the differential value see chapter 4 Parameter description  Parameter no.
32)
Modulo display:
Position values ranging from 0° to 360° are displayed.
Using the "Decimal places" parameter (see  Parameter no. 15) the resolution and the
modulo point of the displayed values are set.

3.2 Position monitoring
(see chapter 3.3 Loop positioning)
Arrows: (see chapter 4 Parameter description  Parameter no. 18)
Arrows are displayed to support the user with positioning as long as the current actual
position value is outside (see chapter 4 Parameter description  Parameter no. 27) target
window1. The arrows represent the shaft's direction of rotation in order to arrive at the set
point. A left-hand arrow means that the shaft is to be rotated counter-clockwise. A right-hand
arrow requires clockwise rotation.
In the modulo display operating mode, the shortest traveling distance to the set point is
displayed.
