Relying on a centralised safety PLC can mean additional cost through complexity of the wiring and safety software. Alternatively, electromechanical
safety devices typically mean lower throughput, longer machine stoppages and extra time required for set-up and maintenance.
The new MiS210 safety option for Unidrive extends the built-in STO with motion safety capability and enables decentralised flexibility with the option of safety over ethernet connectivity.
The MiS210 customer fit option module simply clicks into place, with no screws or other mounting requirements.
Once fitted, the safety functions provided by MiS210 are seamlessly incorporated into the drive’s feature set.
MiS210 enables motion safety decentralisation in combination with the appropriate encoder. This can remove the need for a central safety PLC and the
number of sensors necessary to achieve the required SIL/PL level.
Benefits of safety decentralisation with MiS210 also includes:
Total power shut-down and the consequent reduction of plant productivity is a common challenge with electromechanical safety systems. Deployment of a functional
safety solution can help to alleviate this by safely slowing or stopping a machine to enable human interaction within the process.
MiS210’s safety functionality provides a means to monitor the speed of the motor and if a loss of control is detected will remove the torque using Unidrive’s onboard Safe Torque Off input.
Additionally, removing electro-mechanical safety components can bring further benefits in the form of cost savings, smaller physical footprint and lower acoustic noise.
