Product Description:
The 132L4579 variable frequency drive belongs to the Danfoss VLT EZ FC 321 Automation Drives series. It is intended to regulate the speed of three-phase induction motors in factory automation, HVAC equipment, and material-handling systems by adjusting output frequency and voltage in response to process commands from a PLC or its local keypad. This operating method allows the drive to match motor speed to changing load conditions while supporting controlled starts and stops. It is used where stable motor control is needed without adding a separate external speed-regulation device.
The drive delivers 1.5 HP of mechanical output power, which corresponds to an electrical output rating of 1.1 kW. It accepts a three-phase 525–600 VAC mains supply, allowing direct connection to 575 V class power systems. The enclosure has an IP20 / Chassis rating, so the unit is intended for installation inside a protective cabinet rather than in an exposed location. Local operation, parameter changes, and alarm display are handled through the front-mounted Graphical Local Control Panel. Cooling depends on cabinet airflow, so the surrounding enclosure should provide suitable ventilation for normal operation.
For braking duty, the integrated brake chopper diverts excess DC-bus energy to an external resistor during rapid deceleration. Cable routing is arranged through standard cable entries, which support orderly termination of power and control wiring inside the panel. The electronics use an uncoated PCB, so the drive should be installed in a dry, filtered enclosure where moisture and airborne contaminants are limited. Electromagnetic compatibility measures must be handled at the panel level because the unit has no RFI filter. This arrangement is suitable where external panel design provides the required suppression and environmental protection.
