Product Description:
The S72402-NANANA-NA-030 is a servo drive developed by Kollmorgen for the S700 Servo Drives series. It converts fixed-frequency plant power into regulated three-phase outputs so brushless motors can follow precise torque, speed, and position commands in automated machinery, packaging lines, and test stands. The unit also provides integrated EtherCAT and CANopen links, allowing motion controllers to exchange real-time data without additional plug-in cards.
Electrically, the drive operates from a three-phase AC mains supply of 208 to 480 V and can draw up to 18 kVA while delivering a continuous phase current of 24 Arms to the connected motor. Energy is buffered on a DC bus that may climb to 900 VDC, and insulated-gate modules commutate the bus at 8 kHz to limit current ripple. Brake energy produced during rapid deceleration is first absorbed by an internal 23 Ω resistor that carries 200 W continuously, and any surplus is diverted to an external resistor of the same value. Dual-channel STO terminals interrupt gate signals for functional safety, and the IP20 housing allows installation in ventilated enclosures. With no expansion card installed, the standard PCB still provides EtherCAT and CANopen ports for high-speed network integration.
The chassis is 100 mm wide, 285 mm deep, and 382 mm high with connectors in place, and it weighs 5.5 kg. Acoustic output tops out at 65 dB(A), so additional baffling is seldom needed in a control cabinet. At the rated current, the heat sink must reject 330 W, and forced airflow is recommended when ambient temperatures approach the cabinet limit. For emergency stops or high-inertia loads, an external brake circuit rated for 4 kW can be wired to the dedicated 23 Ω terminals to prevent DC-link overvoltage. The standard PCB is retained, and the cabinet depth leaves clearance for power, STO, and communication wiring while keeping the overall footprint compact.
