Product Description:

The 132L4588 is an AC motor drive produced by Danfoss within the VLT EZ FC 321 Automation Drives series. In automated plants, it regulates induction motor speed so conveyors, pumps, and fans can match changing load requirements while limiting mechanical stress. Its role is to adjust motor frequency and voltage so the driven machine can run at the required process speed. This chassis-mount unit delivers 30 HP of mechanical output and has a continuous electrical power rating of 22 kW. It accepts a three-phase 525-600 VAC supply, allowing direct connection to higher-voltage distribution systems.

The enclosure has an IP20 / chassis rating, so the unit is intended for installation inside a control cabinet where live sections are protected from accidental contact. A built-in brake chopper dissipates regenerated energy during rapid deceleration, which helps control DC-bus voltage when the driven load slows quickly. The drive does not include a mains input or RFI suppression module, and standard cable entries are provided on the wiring plate for line, motor, and control conductors. No additional mechanical adaptations are listed, so wiring can be routed directly within the panel. This arrangement keeps the basic hardware configuration straightforward for enclosed installations.

User interaction is handled through a Graphical Local Control Panel that displays operating data in plain text and supports parameter copying between matching units. The controller uses the VLT AutomationDrive EZ software platform and includes the Standard Language Pack, so English and several common European languages are available at startup. The boards use an uncoated PCB layout intended for clean, temperature-controlled enclosures. If the installation area requires additional sealing against contamination, a coated version should be selected instead.
