The maximum force applied to the piston is referred to as
nominal force F
N
, and it is calculated as follows:
F
N
[N] = A
N
* p
operation
The maximum forces applied to the drive for both direc
tions of movement are calculated as follows: With non−
horizontal mounting position (
α š 0 for linear drives, refer
to Fig.B/2) they are dependent on direction and mass:
F
max+
[N] = + 0.9 * A
N
* p

[N] =  0.9 * (A

This contains the following user data:

= supply pressure
A
N
= nominal piston surface
(e.g. DNCI−25−...: A

=  / 4 * 0.025

)

current tool mass
+ m
current workpi ece mass
α = mounting position
The values for F
max+
and F
max
are calculated in the con
troller. The controller limits the user data to these limit
values and reports a fault if necessary.

The speed and stroke limit values can be deactivated for every force record, so entering 0 is not
permissible.
