Product Description:

The S74802-DNF2-PA is a servo drive module produced by Kollmorgen as part of the S700 Servo Drives series. It interfaces between a three-phase AC supply and a servo motor, shaping current and voltage so industrial axes can follow precise torque, speed, and position commands. By combining control electronics and power switching hardware in one housing, the unit reduces wiring complexity and helps conserve panel space in multi-axis automation cells. This arrangement supports coordinated motion in equipment that requires accurate and repeatable axis control.

Designed for three-phase mains in the 208–480 V range, the drive can absorb up to 35 kVA of apparent power from the supply. At the motor terminals, it provides a continuous output of 48 Arms, while short-term demand is supported by a peak capability of 96 Arms. The IGBT bridge commutates at 8 kHz, which supports responsive current control and lower audible noise. Safety circuitry includes dual-channel STO, which opens two independent paths to remove motor energization when an emergency stop is triggered. Because each thermal cycle stresses the semiconductors, the permitted start rate is limited to 30 starts per hour. Standard printed-circuit boards are paired with an internal F2 fan controller, which helps maintain temperature within rated limits during continuous duty.

Control and monitoring peripherals connect through DeviceNet on slot 1, a fan-controller card on slot 2, and a PosI/O-Monitor module on slot 3. The analog reference input presents 20 kΩ of resistance, which prevents significant loading of PLC outputs, and status values can be returned as ±10 V signals for compatibility with legacy equipment. The housing has a width of 190 mm, a height of 386 mm, and a depth of 244 mm without connectors, and the total mass is 13 kg. The enclosure is rated IP20, so the drive is intended for installation inside a closed panel to protect users from live parts.
