Hi- Frequency Solutions – The All-in-one Solution for High-speed Applications
Whether used as a stand-alone device or as expansion of an existing machine tool, SD2T by SIEB & MEYER offers the perfect basis for driving synchronous and asynchronous spindles or motors with speeds up to 480,000 rpm. All components necessary for the self suffi cient operation as for example operating and display elements as well as motor chokes are already integrated in the device. Furthermore, SD2T can be connected to an existing machine control via analog reference signals (+/-10 V), digital I/Os or USB. The low-voltage version of SD2T is equipped with a galvanic separation of the power unit which protects the sensitive isolation of low-voltage motors. The feature of saving up to 64 motor parameter sets in the drive enables the variable operation with different motors. The devices in table top design are available as low-voltage version with output voltages up to 60 V and as high-voltage version with output voltages up to 220 V.
Features of the Low-voltage Version:
  • Use also in public mains by integrated PFC and compliance with the EMC limit values according to DIN / EN 61800-3, category C1 or DIN / EN 55011 – Limit values for devices of class B / group 1 and 2
  • Controlled intermediate circuit
  • Output voltage up to 3 x 60 VAC
  • Output power up to 600 VA (S1 operation)
  • Short-circuit monitoring
  • No external motor chokes required
  • Protection of the spindle isolation by galvanic separation from the mains supply.
  • Compact and solid table top housing in IP20 design
Features of the High-voltage Version:
  • Output voltage up to 3 x 220 VAC
  • Output power up to 3.8 kVA (S1)
  • Short-circuit monitoring
  • No external motor chokes required
  • Compact and solid table top housing in IP20 design
  • Optionally available as 19“ solution
