Only menu items relevant to standard operation are outlined here.

UX1 to 

UY11

User scaling analog 

input X1 to Y11

Coordinates UX1 to UY11 

as part of an 11-point 

characteristic curve

Set DIP switch 7 to 0, DIP 8 to 1 and DIP 9 to 

1 to allow X and Y coordinates of an 11-point 

characteristic curve to be entered. Otherwise 

these values will be skipped during scrolling. 

11-point characteristic curve: see above.

A freely configurable drive characteristic can be entered and 

saved. For this, set DIP switch 7 to 0, DIP 8 to 1 and DIP 9 to 1.

With other positions of DIP switches 7, 8 and 9, the drive 

characteristic is chosen according to the table in Fig. 7 page 

15.

UX values relate to the value at analog input 2 (AI2). UY values 

are the corresponding values that are issued as setpoints (SI2). 

Here, for example, a UX value of 12% at AI2 results in the output 

of a setpoint of 51%.

It is not necessary to define all 11 points.

If a UX value is not larger than the previous UX value, such 

as when UX4 ≤ UX3, the end of the characteristic curve is 

achieved. UY values can rise, fall or remain the same.

The characteristic curve must not necessarily start at 0% or end 

at 100%.

Endpoints of the characteristic curve do not have to be defined 

with their own coordinates. The first or last straight segment is 

extended if X < UX1 or X > largest UX value. In this example, 

the last straight segment is defined by UX10, UY10 and UX11.

UX5 = 12%; UY5 = 51% (e.g.)
