Frequency inverters or Variable Frequency Drives (VFDs) are used to control the speed/torque or position of electric motors. The wide range of inverters from Mitsubishi Electric offers solutions for all kind of applications, from low to high end with integrated Safe Torque Off (STO) as standard (EN ISO 13849-1 PLd/Cat.3 or EN 61508, EN61800-5-2 SIL2).
The FR-A800 series even support functionalities such as SS1, SS2, SLS, and SOS at PLe and SIL3, which is required in high end machines. Connection to the VFD via Network is possible using a CC-Link IE Safety Communication Function or PROFIsafe.
The FR-E700-SC series inverters for Safety Stop and FR-E700-NC series for CC-Link communication are compliant with the STO (Safe Torque Off) safety function. They can be directly connected to safety programmable controllers, safety relay modules and hardware-based emergency output shut offs and conform to Safety Standards EN ISO 13849-1 Category 3/PLd, EN 62061/IEC61508 SIL2 and European EC Directives.
