How is evaluation performed?
Evaluation is performed upon start. When using the free proĆ
file, the CMAX checks for each target parameter whether it
should use the global setting or the individual parameter.
Individual parameter values shall be used if the respective bit
is set to 1 in the RPV (Record Parameter Control) or the MCPC
(Direct Mode Parameter Control).
Example
Let’s assume 2 types of bulk goods are to be brought to a
collection point and emptied there.
1 2 3 4
1
Position 1: 20 mm (Wait")
2
Position 2: 75 mm (Load 1")
3
Position 3: 145.50 mm (Load 2")
4
Position 4: 205.20 mm (Empty")

Step Task
1 Waiting in a waiting position to start collecting the bulk goods. Upon start the empty
slide uses the default values to travel from the starting position
1 to the first loading
position 2.
2 With increased mass (12 kg) the slide travels to the second loading position 3. AccelerĆ
ation and speed may correspond to the default values.
3 The full container (25 kg) is moved to the unloading position 4. Here the slide needs to
travel based on reduced speed and acceleration values due to the full container.
4 From the unloading position 4 the slide can return to the initial position 1 at full speed.
