Motion control and limits for dynamics
3.18.1
Brief description
Motion control of the axis occurs by means of velocity profiles (Page 70). The velocity
profiles are calculated in accordance with the specifications for dynamics. A velocity profile
defines the behavior of the axis during approach, braking and changes in velocity. During
positioning a velocity profile is calculated, that moves the axis to the target point.
Maximum values for velocity, acceleration and jerk result from the properties of the drive and
the mechanics. These maximum values can be configured in the limits for dynamics. The
limits for dynamics are in effect as limits for every motion generated by means of the
technology object.
The configurable emergency stop deceleration (Page 71) is triggered by the Motion Control
instruction MC_Power or by a technology alarm.
The jerk limit reduces the mechanical load during an acceleration ramp or deceleration ramp.
A "smoothed" velocity profile results.
