RZ/T2M RZ/T2L SIL3 Functional Safety (FuSa)
Presentation Video: Runs without user having to click buttons or setting up programs
RZ/T2M RZ/T2L Functional Safety Automation with ADS protocol
The automated program in the PC is the sample interface below (Pointed by Red Arrow).
Descriptions:
The above image shows all the hardware involved in RZ/T2 Functional Safety system. It is automated so anyone without knowledge of Beckhoff tools and motor CiA402 can operate and showcase it. This system automates multiple steps needed to start up presentation such as opening and setting up twincat tools and pressing button 8 and 10 and so forth. This system requires presenter to press green START SYSTEM on top panel and user/customer to operate EMERGENCY STOP button and thus providing user interactions and participations. 3D hologram improves visual effect in events and presentation.
What is FuSa?
Functional Safety system provides the necessary functionalities to safely stop motor operations and comply with strict SIL3 requirements. By applying already certified RZ/T2M and SIL3 libraries, users can save development resources and reduce certification time.
Why FuSa?
FuSa provides the extra assurance and safety when software fails. With FuSa, whole system is still online and able to restart in a short time compared to shutdown and reset. User is able to control safely the reset process while the system is booting up compared to a regular restart.

Software Functional Safety operations available:
Safe Torque Off (STO) is the foundational functional safety mechanism in drives and servo motors. It reliably disables the motor's power stage, preventing it from generating torque or restarting unexpectedly. When triggered, the motor "coasts" to a stop via natural inertia and friction.
Safe Stop 1 (SS1): The drive performs a controlled, mechanically-braked stop before triggering STO to remove torque. SS1 provides the speed-reduction benefits of an active stop while ensuring that power is safely blocked at standstill.
