Flexibility
- Two option slots for functionality extension and customization (see available option modules)
- Built-in RS485 communications
Safety on-board
-
- Reduced downtime with machine safety
- – Integrated dual safe torque off
- – Meets SIL3 (Safety Integrity Level 3) and PLe (Performance Level e)
Functional Safety
All Digitax HD drives have integrated dual Safe Torque Off (STO) inputs, certified to SIL3 / PLe, providing an elegant and reliable safety solution.
The addition of an MiS250 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).
