Product Description:
The S72402-NANA-NA-030 is a servo drive from Kollmorgen's S700 Servo Drives series. It regulates three-phase permanent-magnet motors in automated machinery by modulating line voltage, monitoring feedback, and providing Safe Torque Off capability through its dual-channel STO circuit. By integrating EtherCAT and CANopen directly on the base unit, the drive connects to higher-level PLCs without an add-on card. This built-in communication setup supports coordinated multi-axis positioning tasks on packaging lines, test stands, and material-handling cells.
The power section is rated for a continuous phase current of 24 Arms, while a short overload window of 2 s allows a peak current of 48 Arms during accelerations or impact loads. That overload capacity helps the drive handle brief demand spikes without forcing the continuous current rating to carry the entire load. A bus capacitance network lets the DC link rise safely to 900 VDC; this is the maximum DC-link voltage before external braking hardware is engaged. Pulse-width modulation occurs at 8 kHz, balancing current ripple against switching losses. When the application runs at rated torque, thermal loss inside the housing reaches 330 W, so cabinet ventilation must remove this heat to keep the electronics below their component limits.
Additional energy-handling features protect both the motor and the supply. If the machine stops frequently, the external braking circuit can absorb up to 4 kW, while an onboard resistor of 23 ohms manages smaller duty cycles without extra hardware. This arrangement allows lighter stop-and-go operation without requiring separate braking hardware for every use case. During standby, dissipation falls to 25 W, helping reduce cabinet temperatures between production shifts. The drive weighs 5.5 kg, allowing it to be panel-mounted beside other S700 units while operating at up to thirty switching cycles per hour without exceeding 65 dB(A) acoustic emission. A residual voltage drop of 6 V on the logic supply keeps the control electronics active long enough for an orderly fieldbus shutdown when mains power is removed.
