Product Description

The Kollmorgen S74801-NA-024 servo digital amplifier is an integral component of the S748/772 series, renowned for its digital servo amplifiers suitable for a vast array of industrial applications. The servo digital amplifier operates on a broad supply voltage range from 3 x 208V to 3 x 480V, making it adaptable to various electrical environments. Its on-board CANopen and EtherCAT interfaces facilitate seamless integration into existing control architectures, while the RS232 and 24V pulse direction interfaces expand its compatibility. The device's internal position controller and the inclusion of Safe Stop STO (Safety Integrity Level 2 according to IEC 61800-5-2 PL d or category 3 according to ISO 13849-1) ensure precise motion control and enhanced safety measures. With three frontside slots for expansion cards and a dedicated memory card slot, the S74801-NA-024 can be customized to meet specific application needs. This servo digital amplifier is engineered to handle synchronous servomotors, linear motors, and asynchronous motors efficiently. The power section's design, which includes a B6 bridge rectifier, integral supply filter, and a soft-start circuit, underscores its reliability in continuous operation. The unit is designed for single-phase supply operation, which is especially useful during setup procedures. It comes with a robust output stage featuring an IGBT module with floating current measurement, ensuring accurate control and reduced electrical interference. Furthermore, its brake circuit is capable of dynamically distributing regenerated power across several amplifiers on the same DC bus link, optimizing energy usage and reducing waste. Its design focuses on practicality, with all shielding connections made directly on the amplifier for ease of installation and maintenance. The S74801-NA-024 is not just a piece of equipment; it's a testament to Kollmorgen's commitment to quality, efficiency, and adaptability in the evolving landscape of industrial automation​​.
