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 RTC The 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 Display The 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 Adaptor This allows the drive to communicate via RS485. This is commonly used for programming if the drive has no keypad.
