Unit of force 

Use:

 

This parameter stores the force unit of the sensor. 

Range:

 N, 

kN 

 

 

Default:

 N 

 

Sensitivity sensor A 

Use:

 

To get the correct force value, the electronic unit has to know the 
sensitivity of the force sensors, that means how much signal the sensor 
will answer by nominal force. Standard for FMS force sensors is 
1.8mV/V. 

Range:

 0.1 

to 

3.0 

Default:

 1.8 

Increment:

 0.1     

Unit:

 [mV/V] 

 

Sensitivity sensor B 

Use:

 Identical 

with 

Sensitivity sensor A

Range:

 0.1 

to 

3.0 

Default:

 1.8 

Increment:

 0.1     

Unit:

 [mV/V] 

 

Min. limit value A+B 

Use:

 

The digital output „Limit value min. A+B“ will be activated if the 
threshold value stored in this parameter is passed under. If the 
parameter contains a zero value, limit switch monitoring is inactive. 

Range:

 -9999 

to 

9999 

Default:

 0 

Increment:

 1 

   

Unit:

 [N,kN] 

 

Max. limit value A+B 

Use:

 

The digital output „Limit value max. A+B“ will be activated if the 
threshold value stored in this parameter is passed over. If the 
parameter contains a zero value, limit switch monitoring is inactive. 

Range:

 -9999 

to 

9999 

Default:

 0 

Increment:

 1 

   

Unit:

 [N,kN] 

 

|A–B| > limit 

Use:

 

The digital output „|A–B| > limit“ will be activated if the difference of 
the measuring values A and B exceeds the value stored here. If the 
parameter contains a zero value, limit switch monitoring is inactive. 

Range:

 -9999 

to 

9999 

Default:

 0 

Increment:

 1 

   

Unit:

 [N,kN]
