Functional Safety
All Unidrive M drives have integrated dual Safe Torque Off (STO) inputs, certified to SIL3 / PLe, providing an elegant and reliable safety solution.
The addition of an MiS210 safety option extends the built-in STO with the ability to safely monitor and/or restrict the scope of motion.
Safety functions include: STO, SBC, SOS, SS1, SS2, SLS, SSM, SLA, SDI, SLP & SES
For maximum flexibility in the safety system architecture, the modules support both wired and network safety connections: CIP-Safety on EtherNet/IP and Safety over EtherCAT (FSoE).

Keypads
 | Remote Keypad RTCThe keypad is remote mountable, allowing flexible mounting on the outside of a panel (meets IP54/NEMA 12). Three line plain text, multi-language LCD keypad for rapid set-up and helpful diagnostics. Battery operated real-time clock allows accurate time stamping of events, aiding diagnostics. |
 | KI Compact DisplayThe display (fitted on M753, optional on M751) ensures access to drive diagnostics even in the absence of network connectivity. Includes 2 rotary switches for hardware setting of the node address for faster commissioning of the motion network. |
 | KI-Compact 485 AdaptorThis allows the drive to communicate via RS485. This is commonly used for programming if the drive has no keypad. |
