DBS servodrives are identified as very high performance converters thanks to a multiprocessor architecture which maximizes the advantages of digital technology: PI regulator for different motors (brushless and induction with both resolver feedback or sensorless), diagnostics, software set up, low speed PC/PLC serial communication, CAN BUS speed reference management. It is a very wide product range (motors up to 75 kW can be fed) with the capabilities to meet any "servo" requirement in conjunction with our FAS, FC and FASY resolver equipped servomotors. DBS is a single axis servodrive with analog (10V) or digital (CAN OPEN according to CIA DS-402) speed reference.

General Features
  • built-in power supply
  • digital speed loop
  • sinusoidal current waveform
  • SMD technology with boards automatically assembled and tested
  • automatic resolver to digital (R/D) resolution switching (from 16 to 10 bit) to achieve high
  • motion accuracy in the whole speed range (from 0 to 10000 rpm)
  • 10 kHz switching frequency up to size 50/140 included, 5 kHz for the other sizes
  • ambient temperature 0 to +40C
  • storage temperature -25 to +55C
  • maximum case depth 370 mm
  • programmable gains of the speed and current loops
  • programmable digital filters (see Application Note GB-4522)
  • built-in fans with internal power supply
  • built-in soft start electronic circuit
  • intelligent IGBT (IPM) power bridge
  • constant motor torque in the whole speed range thanks to dedicated software algorithm

Options
  • software programmable (from 64 to 16384 pulses per electrical revolution).simulated encoder with marker pulse
  • A/D 14 bit converter on the speed reference as alternative to the standard 12 bit version
  • 4 arc/min R/D converter resolution
  • installation and set up keypad
  • PC communication package: see par.2.8.2.1
  • 24 Vdc auxiliary power supply voltage
  • notch filter software (see Application Note GB-4522)
  • high dynamic (HD) special software (see Application Note GB-4526)
  • protection for pollution degree 3 or 4 environment (conductive dust or condensation)
  • accessible DC-Bus from outside (for energy exchange among drives)
