Description

Target window of the force: This is the amount by which the actual force may
differ from the setpoint force in order to be interpreted as still being in the
target window.
The width of the window is thus twice the value transferred, with the target
position in the centre of the window.
The value is specified in

rw

Description

Maximum permitted velocity with active force control.
In this way you can ensure that, if force control is activated by mistake
(e.g.Ăwork item missing), the axis will not undergo uncontrolled acceleration
and move at high speed against a stop.
This parameter is taken into account in all control modes in which the position
controller is not active in the status Operation enabled".
