Product Description:

The S30361-SN is a servo drive produced by Kollmorgen for the S300 Servo Drives series. This unit supplies regulated power and digital control signals to matched servomotors, allowing precise speed and torque management in automated machinery, material-handling axes, and packaging stations. It integrates into a cabinet through a SynqNet network and supports safe torque off circuitry, so motion can be halted without removing mains power. This makes the drive suitable for coordinated axes that require repeatable response during indexing, feed control, and frequent start-stop motion.

The drive accepts an input of 110…230 V AC and converts it to controlled three-phase output for the motor windings. Under continuous duty, it can deliver a phase current of 3 A rms, which sets the thermal limits for cabling and motor sizing. When running from a 230 V supply, the apparent power draw reaches 1.1 kVA, and this value should be considered when selecting branch-circuit protection. Dynamic brake energy can be routed to an internal transistor and dissipated at up to 0.3 kW, which helps prevent DC-bus overvoltage during fast deceleration events. Command words arriving over SynqNet are handled with a setpoint resolution of 14-bit / 12-bit, so small reference changes translate into fine position or speed increments. Functional safety is provided by the hardware-based STO input that disables gate drive to the output stage when activated. That level of control resolution supports smooth networked motion where the master updates commands rapidly.

Baseline losses are minimized through a quiescent dissipation of 12 W, allowing enclosures to remain within temperature limits even when the axis is idle. If braking energy exceeds the internal capability, an external resistor of 66 Ω can be wired to the dedicated terminals to absorb surplus power. The housing, heat sink, and network connectors together weigh 2.7 kg, which helps reduce mechanical stress on DIN-rail or backplate fixtures. The enclosure also supports two RJ-45 ports, high-speed digital I/O, and both mains and 24 V auxiliary fuses. Separate control and power connections help keep cabinet wiring organized in multi-axis installations.
