4.8.8.2.2 Jerk limiting
The maximum acceleration change (jerk) is parameterized via the following ob-
jects. The resolution of the values is 1/100 s
-3
= 0.01 s

4.8.8.2.3 Operating modes of the ramp generator
The behaviour of the ramp generator can be adapted to the requirements of the
application via object cm60 jog ramp mode.
Operational performance of the ramp generator
The bits in cm60 have the following functions:
cm48 is acceleration/deceleration setting for all direc-
tions of rotation (only effective if linear ramps are se-
lected, otherwise cm48-cm51 always apply)
