Product Description:

The S30361-NA-V518 is a servo drive manufactured by Kollmorgen as part of the S300 Servo Drives series. It rectifies and inverts factory power to supply precise current to a matched servomotor, acting as the electrical link between a motion controller and the mechanical load in pick-and-place stations, conveyors, and packaging machines. With a nominal front-end demand of 1.1 kVA, the unit fits light-duty branch circuits while still supporting the rapid motor accelerations used in automated equipment. Because the drive combines power conversion and current regulation in one housing, it also supports compact cabinet layouts where multiple motion axes must be installed in limited space.

Line supply flexibility starts with a nominal input range of 110–230 V, letting the drive connect to single-phase or three-phase mains without an autotransformer. The power stage supplies 3 A rms continuously, and that output should be matched to the connected motor. Switching occurs at 8 kHz, balancing audible noise and switching loss, and when temperatures rise, the device automatically halves output current in a 16 kHz reduced-current mode. Motor windings should present at least 4.3 mH of inductance so the current loop remains stable, and internal devices cap voltage rise to 3.3 kV/µs. Command data and status move over the integrated CANopen onboard interface, simplifying multi-axis network connections. Machine safety is supported by the certified STO (Safe Torque Off) channel, which removes motor torque when an emergency stop is triggered.

The internal DC link reaches 450 VDC, giving headroom for regenerative peaks while staying below the shutdown point. Excess energy is routed to a 66 Ω resistor that absorbs normal braking heat during deceleration. It can dissipate an average of 0.35 kW over one-second intervals and tolerates short pulses of 3 kW, allowing high-inertia axes to stop quickly without opening the overvoltage relay. This braking arrangement helps the drive manage routine deceleration energy without requiring an external resistor for ordinary stopping cycles. These limits support safe deceleration rates and help protect connected motors and wiring from thermal overload.
