MITSUBISHI ELECTRIC Changes for the Better

Drives and Robotics


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.

Servo systems

Servos offer the ultimate in motor performance and controllability. They provide precision motion at incredible speeds including integrated safety functions like Safe Torque Off (STO) according to IEC/EN 61800-5-2:2007. In combination with the function safety unit, the amplifier can be expanded by the additional EN 61800-5-2 safety functions Safe Stop 1 (SS1), Safe Brake Control (SBC), Safe Limited Speed (SLS) and Safe Speed Monitor (SSM). These safety functions can be activated by safe communication via SSCNETIII/H network.


Mitsubishi Electric robots offer class leading technology for both SCARA and articulated arm systems. The robots comply with the latest ISO-10218-1 (2011) standards for robots and robot devices and meet the requirements for PLd of ISO13849-1 Category 3.
