SINAMICS G120D Control Unit CU240D-2 PN-F FO PROFINET and Safety Integrated via fiber-optic cable in push-pull version 6 DI/3 F-DI, 2 DO/1 F-DO, 2 AI HTL encoder interface Degree of protection IP65 Ambient temperature 0 to +45 °C without Power Module SINAMICS CU240D-2 Control Unit for the SINAMICS G120D distributed inverter. The Control Unit performs closed-loop control functions for the inverter. In addition to the closed-loop control, it has additional functions that can be adapted to the particular application through parameterization. The CU240D‑2 Control Units supersede the CU240D Control Units, whereby both versions can be operated with PM250D Power Modules. The Control Units are available in different versions, for example, in CU240D-2 DP, CU240D-2 DP-F, CU240D-2 PN, CU240D-2 PN-F, CU240D-2 PN-F PP (Push Pull: Alternative connection method for the 24 V DC supply voltage and the PN communication) and CU240D-2 PN-F FO (Fiber Optic). The safety function Safe Torque Off (STO) is already integrated into the standard versions of the CU240D‑2 series (CU240D‑2 DP and CU240D‑2 PN). It can be activated either via PROFIsafe or via the safety input. With the fail-safe variants of the CU240D‑2 series (CU240D‑2 DP‑F xx and CU240D‑2 PN‑F xx), the fail-safe SINAMICS G120D inverter provides five safety functions: Safe Torque Off (STO) to prevent the drive from performing active movements, Safe Stop 1 (SS1) for continuous monitoring of a safe braking ramp, Safely Limited Speed (SLS) for preventing dangerous movements when exceeding a speed limit, Safe Direction (SDI) and Safe Speed Monitoring (SSM). An external 24 V DC power supply is required in order to operate the Control Unit. SINAMICS - the integrated drive family for every field of application.
