New guidelines for variable speed drives + motors
While the connection between motor and inverter supply is usually straightforward, there are still a number of issues which need to be carefully considered, as this article explains
The Simatic CPU 315T combines the performance of a standard Simatic CPU with motion control functions that are certified in accordance with PLCopen.
Fast, deterministic controller clock pulses provide isochronous control of up to eight axes.
The configuration tool for the Simatic Technology CPUs, the S7-Technology Step-7 option package, has also been improved.
Version 2.0 includes numerous functions ready to be used in industrial applications.
The new Simatic 315T Technology CPU has the control performance of a standard Simatic CPU 315-2 DP.
The new CPU complements existing Technology; the Simatic 317T Technology CPU is particularly suited for machines requiring high-performance control of many objects.
Both Technology CPUs provide local digital I/O, two Profibus interfaces and motion control functions that are identical in performance and Technology.
The difference is in the number of objects that can be controlled: the CPU 317T manages up to 64 Technology objects.
The new CPU 315T co-ordinates up to 32 objects - which may be any combination of up to eight axes, 16 cams, 16 toggles, eight probes and/or eight external sensors.
Numerous functions ready to be used in industrial applications have been integrated into the Step-7 Options Package S7-Technology Version 2.0, the configuring tool for the Technology CPUs.
"Storing/superimposed commands" and "Higher-level synchronising commands" improve the dynamic response, and newly added read/write access to the drive parameters makes it possible to analyse and change these in the PLC user program.
What's more, data from the TM15/TM17 terminal modules of the Sinamics S120 drives can also be accessed now.
As a result, additional touch probes can be measured and fast cam signals can be issued - with a resolution as high as 1us.
