Product Description:

The S30601-NA-ARM9 is a servo drive manufactured by Kollmorgen and positioned within the S300 Servo Drives series. It functions as the power and control interface between a PLC-based motion system and a synchronous or induction motor. It converts the facility’s three-phase mains to a regulated DC bus and high-frequency pulse output that governs speed, torque, and position in industrial automation lines such as material handling, packaging, and machine tools.

This drive accepts a three-phase supply of 208–480 V, allowing installation on both low- and medium-voltage distribution networks. Under continuous loading, it delivers 6 A rms, while short-duty peaks can reach 12 A rms, giving additional acceleration headroom without thermal derating. Power devices are modulated at 8 kHz, a switching frequency that balances acoustic noise with semiconductor loss. The unit also provides four digital inputs and two analog inputs for flexible command handling. The integrated safety circuit implements STO (Safe Torque Off), which removes motor energy without external contactors. Its 70 mm width and 171 mm depth, measured without connectors, support dense cabinet layouts, and an internal brake resistor assists in absorbing regenerated energy during rapid deceleration.

The DC link can reach 900 VDC, and an overvoltage trip helps protect downstream components. Braking energy is dissipated through an embedded resistor rated at 91 ohms, eliminating the need for a separate chopper in moderate-inertia systems. A continuous power handling capability of 5 kVA matches mid-frame servo motors with inductance no lower than 5.6 mH at 400 V. Communication takes place via onboard CANopen, simplifying drive networking and diagnostic access. Additional characteristics include a voltage rise rate of 5.7 kV/µs at 400 V, a reduced-current switching option at 16 kHz for noise-critical zones, and provision for four digital inputs that can be mapped to index, enable, or quick-stop functions.
