Speed control of a SINAMICS V20 with a SIMATIC S7-1200 CPU viaUSS- and MODBUS-communication.

SINAMICS V20
The SINAMICS V20 is compactly designed andcan be adjusted individually to the requirements of the applicationas well as the demands of the users via various options (such asexternal BOP, connecting cables, filters, brake resistors,shielding, ...). The compact and robust devices are tailored forthe operation of pumps, fans, compressors and conveyor systems, aswell as for simple drive tasks in the processing and productionindustry.

Task
USS communication

• Cyclic write/read access of a SIMATIC S7-1200 to selectedSINAMICS V20 process/control data whose transmission is supportedby a STEP 7 system instruction.

• Acyclic write/read access of a SIMATIC S7-1200 to selectedSINAMICS V20 data that is exchanged via parameter accesses via STEP7 system instruction.

• Connections of up to 64 drives are possible.

MODBUS communication

• Cyclic write/read access of a SIMATIC S7-1200 to selectedSINAMICS V20 process/control data that can be triggered via a STEP7 system instruction via MODBUS register numbers.

• Acyclic write/read access of a SIMATIC S7-1200 to all SINAMICSV20 data that can be triggered via a STEP 7 system instruction viaMODBUS register numbers.

• Connection of up to 128 drives possible (with repeaters,expansion to 988 drives possible).
