Description of the parameters 

The parameter changing mode will be activated by pressing the 

 key for 3 seconds. 

Generally, the parameters are settable using the keys as follows: 

choose 

switch the selections or increase / decrease numeric values 

change the decimal (while inputting a numeric value) 

enter 

 

Find offset A 

Use:

 

The actual force value will be saved by pressing the 

 key for 3 

seconds. This is used to compensate the weigth of the material and the 
roller. The determined value will be shown for 2 seconds and then 
stored under parameter 

Offset channel A.

 

The offset may be determinded also by activating the digital input 

Find offset A

 (terminal b6 resp. 25) for at least 100ms. This procedure 

is equal to executing the parameter function 

Find offset A

 

Calibration A 

Use:

 

In this parameter, using the 

 

 keys you can input the force value 

referring to half of the calibration load you applied to the sensor (force 
feedback value). The processor then calculates the actual gain value 
and stores it under parameter 

Gain channel A.

 

Notice: The input can be aborted with the 

 key. In this case the 

previously saved value remains. 

Range:

 1 

to 

9999 

Default:

 1000 

Increment:

 1 

   

Unit:

 [N,kN] 

 

Find offset B 

Use:

 

The actual force value will be saved by pressing the 

 key for 3 

seconds. This is used to compensate the weigth of the material and the 
roller. The determined value will be shown for 2 seconds and then 
stored under parameter 

Offset channel B.

 

The offset may be determinded also by activating the digital input 

Find offset B

 (terminal b8 resp. 26) for at least 100ms. This procedure 

is equal to executing the parameter function 

Find offset B
