3.1.8 Limitation of setpoint values
In order to position quickly without overshoots when reaching
the position or force setpoint value, CMAX limits setpoint
values for accelerations, etc. which are too high.
During dynamic identification it is determined what maximum
acceleration values allow for overshoot−free positioning.
These values can lie under the physically achievable acceler
ations and decelerations, depending on
the mass, starting
and target positions, etc. The setpoint values specified by the
user for the speed and acceleration are limited to the maxi
mum values determined independently by the CMAX during
positioning.
The CMAX generates a data record during a positioning task,
which compares the user setpoints with the maximum values
determined by
the controller. In the FCT, the used values can
be displayed under the Limits" tab in expert mode.
If dynamic identification is not carried out, the maximum per
mitted values for acceleration must be determined by the
user. By using these determined limits as setpoint values,
overshoot−free positioning is guaranteed.
