Product Description

Unidrive M700 AC drive – Class leading induction and servo permanent magnet motor performance, with real-time Ethernet

Maximize machine productivity through integration with centralized control systems

• Ethernet IEEE 1588 V2 hardware implementation for maximum synchronization accuracy
• Integrated dual port Ethernet switch for easy connectivity
• Up to three SI modules to add position feedback, I/O and fieldbus communications

Maximize machine productivity through shaft performance with any motor technology

• High bandwidth motor control algorithm for open and closed loop induction, synchronous reluctance and PM servo motors with up to 3,300 Hz current loop bandwidth and 250 Hz speed loop bandwidth
• Flexible feedback from robust resolvers to high resolution encoders

Flexible universal encoder port

Increase flexibility and reduce system costs through simultaneously connecting up to three* high performance encoder channels as standard. As an example, the drive can interface with a feedback encoder, reference encoder and provide a simulated encoder output without the need for additional option modules.

• Two universal encoder input channels
  • Support for standard incremental and SinCos encoders, including those with absolute commutation signals
  • Support for communications based encoders with up to 4 Mb rate and line compensation to support long cable lengths of up to 100m
    • Support includes BISS C, EnDat 2.2, HIPERFACE and SSI
  • Support for Resolver for feedback in harsh environments
• One simulated encoder output
  • Position reference for CAMs, digital lock and electronic gearbox applications
  • Implemented through hardware to maximize performance

*The functionality is dependent upon the encoder types being used
