Position control

If a setpoint curve is generated based on acceleration setĆ
points which the drive can’t follow, this can lead to overĆ
shoots at the target position.

With dynamic identification, the maximum attainable speed
as well as the acceleration and deceleration ability of the
drive system are ascertained.
The goal is to make overshoot−free positioning behaviour
possible during positioning.

Examples can be found in the online help of the FCT CMAX
plug−in.

Force control

The target force and force ramp are limited during force conĆ
trol.

Analogue to position control, the start and target values are
displayed on the FCT.

The target value is always the target force. The starting value
is the last setpoint value. If position control was active, the
last setpoint value is always 0 N.

The starting and target positions are also valid, but are not
displayed by the FCT.
The respective actual position is used here.
