Product Description:

The VACON0100-3L-0012-5-R02+SEBJ is an AC variable-frequency drive supplied by Danfoss as part of the VACON 100 Industrial Drives series. Installed between the mains and an induction or permanent-magnet motor, it synthesizes a variable-frequency three-phase output so plant controllers can modulate shaft speed, reduce inrush current, and improve process efficiency. Typical applications include pumps, fans, and conveyors where precise torque regulation and programmable I/O integrate the drive into distributed industrial automation lines.

Housed in the MR4 frame, the inverter fits mid-range cabinets while leaving clearance for airflow and maintaining its IP21 protection rating. Continuous delivery of 12 A supports constant-torque loads at standard duty, and a momentary capacity of 19.2 A for 2 s covers acceleration spikes. When the heavy-duty profile is selected, the output stage sustains 9.6 A and can drive 4 kW at 400 V without additional cooling. An internal control board supplies logic power through a +24 V auxiliary rail that can source up to 250 mA for sensors. The same board provides one analog output and three relay contacts. It also accepts frequency references through two analog channels, providing flexibility for closed-loop or follower configurations.

System interaction is managed through 6 digital inputs, which accept start, stop, and speed-selection signals from PLCs without extra interface modules. Under heavy-duty settings, the drive produces 5 HP at 480 V, while the light-duty curve permits 7.5 HP on the same supply. For regions using metric power ratings, the light-duty output reaches 5.5 kW at 400 V. Functional safety is provided by an integrated Safe Torque Off circuit that satisfies SIL 3, allowing machinery builders to meet Performance Level e without external relays. The safety circuit prevents the drive from generating motor torque when the function is activated.
