Product Description:
The SL3407-00000 is an AC motor drive manufactured by Kollmorgen for the SL3000 AC Motor Drives series. Designed for panel installation, this drive receives fixed three-phase input power and produces a variable-frequency output so plant controllers can regulate motor speed in real time. By managing acceleration, deceleration, and steady-state operation, it supports precise tension, flow, or positioning tasks in automated conveyors, mixers, and pump stations. Its compact enclosure measures 12.35 in high, 9.50 in wide, and 7.06 in deep, which helps it fit standard cabinets while still leaving room for airflow and wiring.
The drive supports motors up to 7.5 HP at base speed. To reach this level, it draws a mains current of 11.0 A and places an apparent power demand of 8.7 kVA on the supply. The displacement between voltage and current is held to a power factor of 0.88, which helps reduce reactive loading and transformer heating. Momentary load spikes are handled by an overload reserve of 150 % for 60 s, allowing the inverter to provide additional torque without immediate protective trips. These electrical limits are coordinated with the internal switching behavior so semiconductor temperatures remain within the rated range.
The controller can deliver a peak phase current of 16.5 A rms during acceleration, and its open-loop start routine generates 150 % torque at 3 Hz to help overcome static load inertia. The braking resistor is permitted to absorb energy for 5 s every 2 min, and its internal network develops 40% torque during each stop. Steady operation at a carrier frequency of 6 kHz causes heat dissipation of 175 W at 6 kHz, a value used when sizing enclosure ventilation. Line protection is provided by a 20 A fuse on the supply feed, and full ratings remain available up to a mounting altitude of 3300 ft.
