Crane?specific applications

Using STARTER, various pre?configured standard applications for various crane applications are configured, for example:

• Single?axis application for the hoist, trolley and gantry with control via PROFIBUS DP, via external I/O terminals or even via just the onboard I/O
• Two?axis application for master?slave closed?loop torque control
• Can be selected using a script screen form (see figure "Script screen form to configure the axis, control and type of master switch")

For users, these solutions are "ready?to?run", i.e. they only have to appropriately set the parameters based on the parameter list (see figure "Parameter assignment using the expert list").

In the case of individual adaptations and expansions, these standard applications can be used as a starting point for "ready?to?apply" applications. The Drive Control Chart (DCC) offers users the best option for making individual adaptations to address their precise requirements.

Optional Drive Control Chart (DCC) packages

With the optional Drive Control Chart (DCC) packages, available for SINAMICS, for simple graphic configurations it is possible to extend the technological functions using pre?defined function blocks. Multi?instance function blocks are selected from a pre?defined library and graphically interconnected using drag and drop. The standard function block library includes a large number of open?loop, arithmetic and logic blocks as well as comprehensive open?loop and closed?loop control functions. DCC provides users with a new dimension to individually adapted specific functions of his machine. Further, DCC is installed in the STARTER commissioning tool.

Note:

DCC must be selected when installing the STARTER commissioning tool. A license is required to generate and edit plans.

The crane DCC blocks are preconfigured using the standard SINAMICS DCC Library. Each individual crane?specific technology (e.g. load?dependent field weakening) is optimally preconfigured in the crane DCC blocks, and encapsulated as individual macro block. These crane DCC blocks are used to process the speed setpoint channel of an individual axis (e.g. hoist with control via PROFIBUS DP after running the script file) and fast monitoring at the cycle level. In this way, clear control loops are presented, and the same crane DCC blocks can always be reused for various axes in various projects.
