SINAMICS S120 · MULTI-AXIS CONTROL VIA PROFINET
A CU320-2 PN control unit for open-loop and closed-loop coordination of SINAMICS S120 Line and Motor Modules.
Siemens 6SL3040-1MA01-0AA0 is a CU320-2 PN Control Unit for multi-axis SINAMICS S120 systems. It communicates with higher-level control through a two-port PROFINET interface using the PROFIdrive V4 profile.
The unit is supplied without a CompactFlash card. Siemens requires a CompactFlash card with firmware V4.4 or higher, and commissioning is performed with SINAMICS Startdrive, STARTER or an AOP30 panel.
