  • Programmable with IEC61131 standard languages

Flexibility

• Two option slots for functionality extension and customisation (see available option modules)
• Built-in RS485 communications

Safety on-board

• Improved productivity 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).
