Product Description:

The S74802-NANAPM-NA-030 is a Kollmorgen servo drive in the S700 Servo Drives series for controlling synchronous and induction motors in automated machinery. It occupies 190 mm of cabinet width, has a height of 386 mm, extends 244 mm in depth, and weighs 13 kg, which helps it fit compact control panels where several axes share limited mounting space. By converting three-phase mains power into controlled output phases, the drive delivers the torque, speed, and position control needed in packaging lines, pick-and-place axes, and gantry systems. It can be used wherever accurate motor regulation is needed for repeatable motion in automated equipment.

The unit accepts input power from 208 to 480 V and provides a continuous phase current of 48 A rms. For short acceleration demands, output can rise to 96 A rms, and the converter operates with a carrier switching rate of 8 kHz to help reduce harmonic torque. The enclosure has an IP20 rating, so the drive must be installed inside a protective cabinet, and the internal bus design limits residual voltage drop to 6 V to support dynamic response. A switch-on frequency of 30 cycles per hour helps limit inrush stress on upstream contactors. The PosI/O expansion card adds fast digital position channels for distributed motion tasks, and this variant uses standard PCBs.

A feeder rated at 35 kVA can supply the inverter, and peak current can be sustained for 5 s before thermal foldback occurs. Functional safety is provided through dual-channel STO, which removes motor torque without delay or auxiliary contactors. During operation, the cooling fan produces 62 dB(A) of sound pressure when the unit runs inside a closed panel. Diagnostic memory stores fault traces so overload events and cabinet thermal behavior can be reviewed against the allowed single-cycle and hourly operating limits. That stored data supports fault analysis after repeated high-load operation.
