Working Principle
The drive converts three-phase AC supply voltage into a regulated DC link voltage through a rectifier stage. The DC link is smoothed by capacitors and then converted back into a variable-frequency, variable-voltage three-phase AC output by an IGBT inverter. The microprocessor controls the output frequency and voltage according to the selected control mode, reference signal, and motor parameters. Built-in protection functions monitor current, voltage, temperature, and motor load. When braking energy is returned from the motor, the built-in brake chopper can dissipate energy through an external brake resistor.

Installation Requirements

  • Install the drive in a clean, dry, and well-ventilated control cabinet.
  • Maintain adequate clearance above and below the drive for cooling airflow.
  • Use correctly sized supply cables, motor cables, and protective devices.
  • Connect the PE grounding terminal according to local electrical standards.
  • Keep motor cables separated from signal and communication cables.
  • Configure motor nameplate data before starting the motor.
  • Select the correct control mode, reference source, and I/O configuration during commissioning.
  • Install an external brake resistor only if dynamic braking is required and the resistor rating matches the application.

Precautions for Use

  • Do not operate the drive with missing or loose terminal connections.
  • Do not exceed the rated input voltage, output current, or ambient temperature.
  • Verify that the IP20 enclosure is installed inside a suitable cabinet.
  • Do not connect power factor correction capacitors on the motor output side.
  • Allow the drive to cool before performing maintenance.
  • Back up parameters before firmware updates or major configuration changes.
  • For exact rated current, power rating, option card compatibility, and environmental data for NXL00045C1N1SSS00, refer to the official Vacon NXL user manual and nameplate.
