SEW MDS60A0055-5A3-4-00

Product Introduction:
The MDS60A0055-5A3-4-00 is a frequency inverter from SEW-EURODRIVE’s MOVIDRIVE MD 60A series, specifically designed for SERVO-type applications. The “MDS” prefix identifies this unit as a SERVO operating mode inverter, which means it is configured for current flux control (CFC) with resolver feedback, optimized for synchronous motor drives. The “60A” designates the MD 60A platform version. The “0055” indicates a recommended motor power of 5.5 kW. The “5A3” specifies a three-phase supply voltage of 380–500V with an integrated input filter. The “4” denotes four-quadrant operation capability with a built-in brake chopper. The “00” suffix indicates the standard configuration.

Working Principle:
The inverter converts three-phase AC input power through a rectifier stage into DC bus voltage, which is smoothed by capacitors. The IGBT inverter stage synthesizes variable-frequency, variable-voltage PWM output to control the connected synchronous motor. In SERVO mode, the resolver attached to the motor provides real-time rotor position feedback, enabling precise field-oriented current flux control (CFC). The control algorithm decouples flux and torque components for independent regulation, achieving high dynamic response and positioning accuracy.

Installation Requirements:

  • Mount vertically inside a control cabinet with at least 100 mm clearance above and below for cooling airflow
  • No side clearance required; units can be lined up in rows
  • Use shielded motor cables with 360° shield grounding via the power shield clamp
  • Connect the resolver cable to the appropriate option card interface
  • Connect braking resistor to dedicated braking terminals for 4Q operation
  • Ensure ambient temperature remains within -10°C to +40°C operating range

Usage Precautions:

  • Perform motor initialization and auto-tuning after connecting a new motor
  • Use MOVITOOLS software or DBG11A keypad for parameter configuration and commissioning
  • Never connect or disconnect power or motor cables while the inverter is energized
  • Monitor fault codes via the LED display or MOVITOOLS software
  • Clean heat sink fins regularly to prevent overheating
  • Wait at least 5 minutes after disconnecting main power before performing maintenance to allow capacitor discharge
  • Verify supply voltage stability within ±10% tolerance before operation
  • Ensure the resolver is properly connected and calibrated before enabling SERVO mode
