Product Description:

The 132L4606 is a variable-frequency drive manufactured by Danfoss and assigned to the VLT EZ FC 321 Automation Drives series. In industrial automation, this drive regulates induction motor speed so that pumps, fans, and material-handling equipment run only as fast as the process demands, reducing energy consumption while maintaining torque stability. By varying output frequency and voltage, it supports controlled acceleration and deceleration instead of abrupt full-speed starts. That operating pattern can help limit mechanical shock on belts, impellers, and other driven components. It can also maintain more consistent process flow when the load varies during operation.

This model has an enclosure rating of IP66 / NEMA 4X Backplate, allowing direct machine mounting without an additional enclosure in many wet or dusty areas. It accepts a three-phase 200 to 240 VAC supply and delivers a continuous mechanical output of 18.5 kW, equivalent to 25 HP, for mid-range conveyor and blower duties. Harmonic emission is limited by an integrated RFI Class A2 (C3) filter, which helps reduce conducted interference on commercial mains. Operators configure parameters through the standard Graphical Local Control Panel, which provides local access to operating values and setup changes. The sealed housing supports placement closer to the driven equipment, which can shorten motor lead routing in machine-mounted installations.

Cable routing uses standard cable entries, and no supplementary A, B, C0, C1, or D options are installed. Dynamic braking is handled internally by the brake chopper, which can absorb regenerated energy during moderate-inertia deceleration. The control electronics use an uncoated PCB, and both adaptation B and coating selections remain at their default values. The absence of extra entry and mains options keeps the enclosure layout simple for standard installations. This arrangement suits general-purpose automation tasks that need sealed construction and basic interference control.
