Product Description:

The S74802-SNF2-F2 is a digital servo drive built by Kollmorgen as part of the S700 Servo Drives series. Designed for cabinet installation, the module converts incoming three-phase mains into a regulated output that follows motion commands from a higher-level controller. Its role in industrial automation is to supply fast current loops and safety functions so that permanent-magnet servo motors can execute precise positioning, synchronized line shafts, and dynamic tension control across packaging, converting, and material-handling systems.

Electrical performance is anchored by a rated output of 48 Arms, allowing medium-frame motors to accelerate quickly without saturation. The power section accepts a wide mains span of 208–480 V, so the same hardware can be used on either 230 V or 460 V plant networks. During continuous operation, it may draw up to 35 kVA, and that figure guides breaker sizing and cabinet thermal design. Fast pulse-width modulation at 8 kHz minimizes motor acoustic whine and improves current-loop bandwidth. For functional safety, a dual-redundant shutdown path is provided; the integrated dual-channel STO disconnects gate signals within milliseconds to meet SIL-rated stop requirements.

The F2 fan module activates when internal heat sinks reach 65 °C, and with the fans disabled the electronics still dissipate only 24 W, reducing standby cabinet temperature rise. The fan controller occupies the second option slot identified as an F2 board and is monitored by the drive. Acoustic output peaks at 62 dB(A), permitting placement near workstations without exceeding typical factory noise limits. Control electronics, I/O, and the fan circuit are powered from an auxiliary 24 V DC supply, so the main bus can be de-energized during service. A cast chassis keeps total mass to 13 kg while providing rigidity over the 386 × 190 × 244 mm envelope.
