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
  • large nominal voltage range 1 x 110V-10% ... 3 x 480V+ 10%. With S748/772 and mains voltage below 300V set parameters NONBTB=3 and VBUSBAL=1.
  • TN-network or TT-network with grounded neutral point, 42000 A max. symmetrical current rating, connection to other supply types only via isolating transformer
  • Single-phase supply operation possible (e.g. for setup)
  • Mains choke in case of asymmetry >3% of the mains voltage
  • Fusing: (e.g. fusible cutout) to be provided by the user, see Fuses
  • Building Power Supply Groups

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 (see page DC Bus link in parallel).
  • The sum of the rated currents for all of the servo amplifiers connected in parallel to an S701...S724 must not exceed 48 A (parallel to S748/772 not more than 96Arms).
  • 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 S700 with 400/480V rated voltage and max. 24A rated current.
Possible Combinations S700 with HWR < 2.00 S700 with HWR >= 2.00 S300
S700 with HWR < 2.00 yes no no
S700 with HWR >= 2.00 no yes yes

HWR = Hardware Revision Number (check nameplate)

Control Circuits

  • Digital current controller (space vector, pulse-width modulation, 62.5 µs)
  • Adjustable digital speed controller (62.5 µs)
  • Integrated position controller, with adaptation possibilities for all applications (250 µs, optionally 125 µs)
