Frequency converter

Environment conditions:

  • Climatic version: U5 (temperate)

  • Ambient temperature: minus 15°C to +55°C

  • Relative humidity: 5% to 95%

  • Atmospheric pressure: (84.0-106.7) kPa 

  • Dust concentration in air: max. 500 mg/m3

  • Altitude: 1000m below sea level to 1000m above sea level

Frequency converter circuitry provides:

  • Conversion of 400(690)V/50Hz mains power into 0-400(0-690)V/0-500Hz at downstream electric motor

  • Control by binary and analogue signals

  • Communication by Profibus, DRIVE-CLiQ (option – Profinet) 

  • Performance parameters indication at the operator’s panel

  • Prevention of branch line self-engagement at brief (max. 0.1s) mains voltage rise up to 150% of rated value

  • Output circuit leakage current protection

  • Contactor interlock upon overcurrent or overheating trip

  • Electric motor temperature monitoring
