SINAMICS G120D Control Unit CU240D-2 PN-F PP PROFINET and Safety integrated in push-pull design 6 DI/3 F-DI, 2 DO/1 F-DO, 2 AI SD/MMC card interface HTL encoder interface Protection class IP65 Ambient temperature 0 to +50°C without Power Module Control Unit SINAMICS CU240D-2 for the decentralized converter SINAMICS G120D. The converter is controlled by the Control Unit. In addition to the control, other functions are available that can be adapted to the respective application by appropriate parameterization. The Control Units CU240D-2 replace the Control Units CU240D, whereby both versions can be operated with the Power Modules PM250D. The control units are available in different versions: CU240D-2 DP, CU240D-2 DP-F, CU240D-2 PN, CU240D-2 PN-F, CU240D-2 PN-F PP (Push Pull: alternative connection technology for the DC 24 V supply voltage and PN communication) and CU240D-2 PN-F FO (Fibre Optic). The Safe Torque Off (STO) safety function is already integrated in the standard versions of the CU240D-2 series (CU240D-2 DP and CU240D-2 PN). This can be activated both via PROFIsafe and via the safe input. The fail-safe SINAMICS G120D converter offers five safety functions with the fail-safe variants of the CU240D-2 series (CU240D-2 DP-F xx and CU240D-2 PN-F xx). These include safe torque off (STO) to protect against active movement of the drive, safe stop 1 (SS1) for continuous monitoring of a safe braking ramp, a safely limited speed (SLS) to protect against dangerous movements when a limit speed is exceeded, a safe direction of rotation (SDI) and safe speed monitoring (SSM). An external 24 V DC power supply is required to operate the control unit. SINAMICS - the consistent drive family for every application.
