AKD BASIC Electrical Information

Power Supply

Auxiliary supply voltage Mains power supply
  • From an external 24V DC power supply unit
  • Electrically isolated
  • Internal fusing
  • Fusing: (e.g. fusible cutout) to be provided by the user, see Fuses
  • 2 device types for large nominal voltage range 1 x 120V-10% to 3 x 480V+ 10%.
  • Industrial mains, 42000 A max. symmetrical current rating
  • Single-phase supply operation possible
  • Mains filters for AKD-xzzz06 types see page Mains Filter
  • Fusing: (e.g. fusible cutout) to be provided by the user, see Fuses

  • Brake circuit: with dynamic distribution of the regenerated power between several amplifiers on the same DC bus link circuit.
  • Internal Brake Resistor standard in most types, external Brake Resistor if required.
  • DC bus link voltage can be connected in parallel
  • Only servo amplifiers with mains supply from the same mains (identical mains supply voltage) may be connected by the DC bus link
  • KCM Capacitor Module for AKD with 400/480V rated voltage and max. 24A rated current.
  • Digital current controller (670 ns)
  • Digital speed controller  (62,5 µs)
  • Digital position controller (250 µs)
