Applications
In combination with the PLCopen-compatible motion control blocks, the technology controllers are particularly well suited for coupled motion sequences of multiple axes.
Along with position-controlled single axis positioning, primarily complex, synchronized motion sequences are possible, e.g. gearbox synchronization, cam disk synchronization and print-mark correction. The synchronized axes can be combined to a virtual or actual master.
For path interpolations, powerful PLCopen-compatible functions are available that support various standard kinematics (SCARA, roll picker, articulated arm robot, delta-picker 2D/3D).
The isochronous PROFIBUS DP(DRIVE) permits control of the axes over a digital bus system. The two ther interfaces (PROFINET and PROFIBUS) can be used for user-friendly parameterization and commissioning of the drives from a PC/programming device.
As a result, the technology controllers can be used for a host of new applications, e.g.:
-
Processing/assembly lines
-
Throughput machines
-
Handling systems
-
Cross-arms
-
Gantries
-
Filling
-
Wrapping
-
Roll feeds
-
Flying shears
-
Carton erectors
-
Labeling machines
-
Cross cutters
-
Hydraulic presses
-
Palletizers
