Product Description:
The SV3405-11000 is a flux vector drive built by Kollmorgen for the SV3000 Flux Vector Drives series. Designed as a three-phase AC inverter, it converts fixed mains power into a variable-frequency, closed-loop output that maintains precise torque on properly tuned motors in industrial automation. An internal incremental encoder interface accepts two-channel quadrature feedback, allowing the controller to track shaft position for vector calculations without external modules. The encoder accepts 5 V DC differential signals at up to 200 mA and supplies the position information needed for speed and slip compensation. Applications include packaging lines, material-handling conveyors, and pump skids that require stable speed regulation and fast dynamic response.
For operation in washdown and dusty environments, the housing carries a NEMA 4/12 rating. Total drive heat loss is limited to 150 W, allowing standard panel cooling to manage the generated heat. The power stage has an input power factor of 0.95, which reduces reactive current loading on the supply. Peak motor acceleration current reaches 11.4 A RMS, providing additional current during rapid changes in speed or load. During continuous operation, the inverter supplies 7.6 A RMS, corresponding to an apparent output of 6.0 kVA. The integral brake chopper can absorb regenerative energy equal to 50% of the developed torque, helping prevent DC-bus overvoltage during deceleration.
The mains input section is rated for 10.4 A and transfers incoming power to the drive’s DC link. Its inverter stage supports a motor output of 5 HP, making the drive suitable for moderate-power industrial axes and rotating equipment. When paired with a properly tuned motor, the control loop is optimized for a synchronous speed of 1800 rpm, allowing full-load torque production with minimal slip. The closed-loop architecture adjusts output frequency and current in response to changing motor load, which helps maintain stable shaft speed during demanding operating cycles. Regenerative energy from standard stopping profiles can be handled by the integrated chopper, reducing the need for external dynamic braking components in typical installations.
