Example: Closing weight = 4 kg
Desired static force limit CLOSE = 150 N
The counterweight of 4 kg corresponds to a force of 40 N. The force limit then has to be adjusted 
to 150 N – 40 N = 110 N.
In the factory setting, the closing force is preset to a minimum value (see section Proles and 
adjustment ranges (Page 329)).
Limit force end CLOSE
This force serves to overcome the cutter distance in the closing direction.
A higher force is often required to overcome the cutter distance than for the rest of the distance 
the door travels.
This parameter is eective in the closing direction when the door is within the cutter distance.
Adjustment ranges
The parameter can be adjusted in accordance with the adjustment ranges of the parameters (see 
section Proles and adjustment ranges (Page 329)). The value of the parameter must be selected 
so that the cutter distance is overcome in the closing direction.
In the factory setting, the closing force is preset to a minimum value (see section Proles and 
adjustment ranges (Page 329)).
5.9.4.3 Parameter assignment
The tables below show all the parameters that are available via the PKW interface. The 
parameters are generally subdivided into:
• Driving parameters
• Fieldbus parameters
• Other parameters
• Calibration and function parameters
• Obstruction and reversing parameters
• FBLOCK parameters
• Basic parameters
Note
Write-protected parameters (read only) are indicated in the documentation by an "r" before the 
parameter number. 
Read / write parameters can be changed, and are indicated by a "p" before the parameter number.
