The individual predefined variables are:
Traversing distance
Traversing time
Dwell time
Mass to be moved
(without motor mass)
Constant friction
Horizontal axis
In addition, a power module is to be selected and the maximum infeed power calculated.
Constraints/specification of the duty cycle
Traversing profile – Example 1
The form of the traversing profile during time Δt
suitable traversing profile must first be specified.
The following example shows a traversing profile that is the simplest to implement: With this
profile, only one constant acceleration phase and one constant deceleration phase are
required to reach position s
the shortest positioning times.
