Product Description:
The S7240F-NANANA servo drive is manufactured by Kollmorgen as part of the S700 Servo Drives series. Designed for industrial automation, it converts DC-link voltage into a controlled three-phase output so motion controllers can regulate the position, speed, or torque of synchronous and asynchronous machines. It interfaces directly with higher-level motion controllers over real-time fieldbuses and simplifies axis integration within densely populated control cabinets.
With a continuous output current of 24 A RMS, the drive supplies torque to medium-frame servo motors while remaining within its thermal limits. Its three-phase input accepts 208 to 480 V AC mains power, and the power stage operates at a switching frequency of 8 kHz to minimize current ripple. With a line-side power demand of 18 kVA, the drive can be connected to appropriately sized cabinet feeders. The insulated-gate transistors withstand a differential voltage rise rate of 6.9 kV/µs at 480 V, helping limit stress on motor insulation. Stable current control requires a minimum motor inductance of 1.4 mH. Dual-channel safe torque off is integrated for safety, while EtherCAT and CANopen communication are available without an expansion card.
The internal braking resistor absorbs 200 W continuously, while a separate bus can dissipate 4 kW when suitable external hardware is installed. During rapid deceleration, the braking system can tolerate short-term pulse power of up to 30 kW before reaching its duty-cycle limits. The electronics dissipate 330 W as heat during full-load operation, so forced-air ventilation is advisable to keep the enclosure temperature within its permitted range. The housing measures 348 mm high, 100 mm wide, and 243 mm deep, and it weighs 5.5 kg to support practical panel mounting. Its internal resistor has a resistance of 23 Ω for braking current control. Airborne noise is limited to 65 dB(A), and the circuit boards are available with a standard or protective coating for use in demanding atmospheres.
