MDR91B-.. block-shaped supply and regenerative modules

Characteristics

  • Weighted distortion factor < 19%.
  • High EMC category C2.
  • Small, lightweight and compact design.
  • Cheaper components.
  • Low losses due to block-shaped switching of the IGBTs.
  • High overload capacity of 250% of the nominal power rating.
  • Internal precharging of the DC link capacity via the DC 24 V supply.
  • The regenerative function is automatically inhibited in motoring operation.
  • Increased tolerance to long supply system cables with increased inductance.
  • Communication with the connected axis modules via module bus.
  • Automatic adaptation to the power supply, diagnostics, and data storage function with the MOVISUITE® engineering software.
  • Connection via EtherCAT®/SBusPLUS to MOVI-C® CONTROLLERs and higher-level controllers (PROFINET, EtherNetTM/IP, Modbus TCP/IP, EtherCAT®).
  • Data storage in the MOVI-C® CONTROLLER, automatic data recovery in the event of device replacement.
  • Measurement of energy and power flow.
  • Scope function for detailed diagnostics.
  • Braking resistor can be connected, regenerative function can be deactivated.
