62.5 μs current loop
250 μs position and speed loop

Up to 16 kHz switching frequency
Supports a wide range of feedback technologies including Quadrature, SinCos (including absolute), SSI, BiSS, EnDat (up to 4 Mb with EnDat 2.2) and resolvers
Maximum performance package with high torque density, low inertia Unimotor hd servo motors
Analog and pulse/direction control for centralized motion
Advanced 1.5 axes Motion Controller, key features include:
- Real-time tasks
- 250 μs cycle time
- Motion profile generator

DIN rail alignment
Kits for easy multi-axis installation
Single motor cable and electronic motor name plate for fast set up
Seamless motor-drive pairing with Unimotor hd servo motors
Easy access pluggable connectors
Rapid commissioning with the Connect PC tool and SD cards
Machine Control Studio provides a flexible and intuitive environment for programming automation and motion control features
- Programmable with IEC61131 standard languages

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).
