Product Description:

The S7242F-NAF2NA-035 is a Kollmorgen servo drive in the S700 Servo Drives series. It regulates current and voltage for matched servo motors while monitoring motion safety functions in automated equipment. Built-in EtherCAT and CANopen communication ports provide deterministic data exchange with higher-level controllers used in packaging, printing, and robotic machinery. This makes the unit suitable for axes that need coordinated speed, torque, and positioning performance in a cabinet-mounted drive platform.

The housing is 100 mm wide, 348 mm high, and 243 mm deep without cable connectors, which helps when planning cabinet spacing and cable routing. These dimensions support dense panel layouts while still leaving room for airflow and wire entry. With a mass of 5.5 kg, the module remains manageable during panel installation. During continuous operation, it carries a rated phase current of 24 Arms, and switching losses are removed as 330 W of thermal dissipation with assistance from the integrated F2 fan, which can remain active at ambient temperatures up to 65 °C. Operational noise is limited to 65 dB(A). Internal dynamic braking energy is absorbed by a 23 Ω resistor rated for 200 W, and the power stage drops only 6 V at nominal load.

On the supply side, the drive draws up to 18 kVA from the mains and charges a DC link that can rise to 900 VDC. From that bus, the inverter can deliver a peak phase current of 48 Arms for short acceleration events, and it switches at a carrier frequency of 8 kHz to balance motor acoustics with switching losses. That combination supports short bursts of higher torque on high-inertia axes without raising the continuous current rating to the same level. Applications that require longer braking cycles can use an external 4 kW resistor to reduce the load on the internal braking network. Dual-channel STO inputs provide torque suppression without contactors, which supports safety functions that require motor torque to be removed quickly.
