Product Description:

The SL3401-01000 is an AC motor drive manufactured by Kollmorgen as part of the SL3000 AC Motor Drives series. It supplies variable-frequency power to standard induction motors, allowing closed-loop speed and torque regulation in automated material-handling, pumping, and processing lines. By integrating the rectifier, inverter, and control electronics into a single housing, the unit simplifies cabinet wiring and reduces the number of external components needed around the motor control section. This arrangement also supports coordinated motion control with PLCs and other plant devices where stable speed response is important during changing load conditions.

The drive’s chassis depth is 7.06 in, and it is protected by a NEMA 4/12 enclosure for use in areas exposed to dust or non-corrosive splashing fluids. An input power factor of 0.95 reduces reactive current on the supply bus, which helps the upstream electrical system operate more efficiently. The inverter delivers a continuous mechanical output of 1 HP and can tolerate an overload of 150% for 60 s, giving added margin during acceleration or brief process disturbances. Overall dimensions of 12.35 inches in height and 9.5 inches in width permit installation on many 14-inch-deep panels, and the 1.4 kVA rating fits typical 3-phase 230 V feeders protected by a 6 A KTK-6 line fuse.

Total heat loss is limited to 50 W, and an internal fan forces air across the heat sink to keep semiconductor temperatures within safe operating limits. The power stage can source a peak output current of 2.7 A RMS while its continuous phase current remains at 1.8 A, matching motors that draw about 1.4 kVA at base speed. High-torque starts are supported with 150% at 3 Hz, allowing loaded conveyors to overcome static friction without external soft starters. Additional internal dynamic-brake circuitry provides 150% regenerative torque, allowing the drive to decelerate inertial loads without exceeding bus voltage limits.
