Power Supply

Auxiliary supply voltage Mains power supply
  • From an external 24V DC power supply unit
  • Electrically isolated
  • Internal fusing
  • Large nominal voltage range
    1 x 115V AC (S40xM only, unearthed operation is permitted)
    3 x 115V AC (S40xM only, unearthed operation is permitted)
    1 x 230V AC (S40xM only, unearthed operation is permissible)
    3 x 230V AC (all types, unearthed operation is permissible)
    3 x 400V AC (S44xM only, TN-network or TT-network with earthed neutral point)
  • Fusing: (e.g. fusible cutout) to be provided by the user, see Fuses

DC Bus Link

  • Brake circuit: with dynamic distribution of the regenerated power between several amplifiers on the same DC bus link circuit
  • Internal Brake Resistor as standard, external Brake Resistor if required.
  • DC bus link voltage can be connected in parallel
  • The sum of the rated currents for all of the servo amplifiers connected in parallel to an S400 Master must not exceed 40 A
  • 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 S400 with 400V rated voltage.

Control Circuits

  • Digital current controller (space vector, pulse-width modulation, 62.5 µs)
  • Adjustable digital speed controller (62.5 µs or 250 µs)
  • Integrated position controller, with adaptation possibilities for all applications (250 µs)
