3. Use parameter p0892 to specify how long the retraction speed is to be applied.
4. Select the OFF ramp with parameter p0891.
Figure 8-29 OFF ramp with "extended retract"
The retraction speed is not approached suddenly. It is approached via the OFF3 ramp.
Parameter p0893 supplies the ramp-function generator with the setpoint for the ESR
retraction speed which is actuated by an OFF3 ramp in the case of drive-autonomous
motions. The safety setpoint velocity limiting p1051/p1052 and the normal velocity limits
r1084/r1087 are active.
