Ethernet-based servodrive - Kollmorgen

The Ethernet-based Advanced Kollmorgen Drive (AKD) is available for 120/240-Vac or 480-Vac operation, with a power range of 3 to 24-Arms continuous current, 9 to 48-Arms peak. The unit supports a variety of feedback devices — mart feedback devices (SFD), Endat, BiSS, Analog sine/cos encoders, incremental encoders, Hiperface, and resolvers — and Ethernet Motion buses — EtherCAT, CANopen, and Modbus/TCP.

The AKD’s autotuning algorithms automatically adjust all gains, including patent-pending observers. This function also provides immediate and adaptive responses to dynamic loads and promises precise control of all motor types.

The AKD features 27-bit resolution, a powerful dual processor system that executes servoalgorithms with high resolution for very-fast settling times, torque loop updates in 0.67 μsec, 6.25-μsec velocity, and 125-μsec position loops.

Additional features optically isolated I/O that reduces noise and eliminates the need for additional hardware; SIL-qualified, overvoltage, current, and temperature detection; option cards that increase available I/O and add NVRAM; and multiaxis machine-control capability.
