ESR Pollmeier offers AC servo drive packages with brushless motors and full digital servo drives.

Features of the servo drives

  • Compact drives for control cabinet installation
  • For direct connection to 230 VAC or 3 × 400/480 V three-phase mains
  • High dynamics and control quality through signal processor for digital control of current and speed (controller cycle time 62,5 µs)
  • Rapid acceleration, deceleration and reversing of the servo motor by momentary current increase to up to three times the rated current
  • Position control loop integrated (micro-controller cycle time 1 ms)
  • Technology functions (positioning control etc.) integrated
  • Various operating modes, including interpolated position mode
  • On request with integrated positioning control with 500 program command blocks
  • Easy wiring
  • Switching frequency 8 kHz or 16 kHz selectable for optimum dynamic characteristics and small motor power loss
  • Comfortable installation using a personal computer with the SPP Windows software
  • Access to drive parameters via drive server (OPC)
  • CiA 402 also available for other interfaces, e. g. EtherCAT, Profinet, Modbus, USB, and serial interface

Features of the servo motors

  • AC motors up to 16 kW/70 Nm
  • High dynamics
  • Wide speed control range
  • High power density through rotor with rare earth magnets
