The controller cards


The KW-R controller cards individualise the KW compact inverters. Seven variants are available which differ in terms of drive control functions and interfaces.


Two KW-R add functional safety to the process. Thanks to the FSoE protocol, they enable safe movements up to Performance Level (PL) d and Safety Integrity Level (SIL) 3. The “Functional Safety” option increases safe movement and optimum protection at the man-machine interface.
