Drive Control Block (DCB) Extension in SINAMICS S120 is part of the Advanced Technology Functions. DCB Extension is an extension of the block scope, which can be used as additional, autonomous library in the DCC-Editor. The additional libraries can be generated using DCB Studio.
With the DCB Extension, the "GMC" additive block library for motion control is available for SINAMICS S120. This library contains a collection of new motion control blocks for typical tasks, such as positioning, referencing/homing, aligning, catching-up/stopping, cams, engaging/disengaging, gearing and many more Using these blocks, the following positioning and synchronous operation functions can be implemented with SINAMICS DCC in the SINAMICS S120 drive system:
Further, with DCB Extension there is the possibility of creating user-specific blocks. The blocks are then created in DCB Studio in a high-level language. They are available in SINAMICS DCC as a separate library and can be combined with the DCB standard library blocks.
