Product Description:
The S72402-PBNANA-NA is a servo drive from the Kollmorgen S700 Servo Drives series intended for cabinet installation where precise closed-loop motion is required. Acting as the power and control stage, it accepts three-phase industrial mains, rectifies the incoming supply, and energizes synchronous or induction motors for accurate torque, speed, and position control in packaging lines, conveyors, and robotic joints. By integrating safety and multi-protocol networking in one package, the device reduces panel density while supporting a range of automation architectures.
The housing measures 100 mm wide, 348 mm high, and 243 mm deep, which supports cabinet installation in compact control panels. The drive delivers a rated output current of 24 Arms for continuous motor operation, while momentary demands can be met with a peak output of 48 Arms. When connected to three-phase mains, the unit draws 18 kVA and rectifies it to a DC link that may rise to 900 VDC. Pulse-width modulation is generated at 8 kHz to help minimize motor torque ripple. The input range of 208–480 V supports common plant voltages. A PROFIBUS module occupies slot 1, while EtherCAT and CANopen are already present on the baseboard. Braking energy is routed through a 23 Ω internal resistor, and an external resistor bank rated at 4 kW can be attached. Idle operation dissipates 25 W, rising to 330 W under rated load, which is important for enclosure ventilation.
The drive also contains a dual-channel STO circuit that removes gate signals through two independent paths, providing integrated safety without external contactors. Its integrated brake chopper handles up to 200 W of continuous regenerative power before the external 4 kW resistor engages. The assembly weighs only 5.5 kg. Standard PCBs with conformal coating resist cabinet moisture and contaminants. Because the baseboard already carries EtherCAT and CANopen, the option slot can be reserved for future I/O or encoder expansion without changing the footprint or cooling requirements.
