Product Description

The S72401-NA, a powerhouse within Kollmorgen’s S7 series, is engineered to enhance industrial automation with its superior performance. With a rated supply voltage accommodating a broad spectrum from 208V to 480V and the ability to handle an impressive continuous rated current of 12 Arms, this servo digital amplifier is designed for applications that demand high power and precision. The versatility of the S72401-NA is not just in its power delivery but also in its peak current capabilities, reaching 48/72 Arms for approximately 2 seconds ± 3%. Such dynamic performance is essential for applications requiring swift torque responses. The servo digital amplifier operates at a switching frequency of the output stage at 16 kHz, which translates to a finer control of motion and smooth operation across a range of speeds. Equipped with a formidable voltage rise speed of dU/dt at 6.9 kV/µs for 3x480V, the S72401-NA ensures rapid response times, which is crucial for time-sensitive applications. The thermal dissipation is managed effectively, with a maximum of 330 W at rated current, indicating the drive’s efficiency in maintaining optimal temperatures during high-load operations. From a practical standpoint, the S72401-NA is relatively compact, weighing 5.5 kg and with a height of 382 mm including connectors, making it suitable for various industrial setups without demanding excessive space. The noise emission is capped at a maximum of 65 dB(A), which is considerate for maintaining a more comfortable working environment. Kollmorgen has crafted the S72401-NA with a focus on user-friendly experience and safety. The digital amplifier includes provisions for overvoltage switch-off and brake circuit technical data, ensuring reliable performance and adherence to safety standards. This makes the S72401-NA a reliable and essential asset in advanced industrial automation systems.
