Product Description:

The S30361-NA is a compact servo drive produced by Kollmorgen for the S300 Servo Drives series. It mounts in a control cabinet and interfaces with machine controllers through its onboard CANopen port, giving deterministic command exchange and diagnostic access. By rectifying the incoming single- or three-phase supply and generating a high-frequency switching output, the unit delivers closed-loop speed and torque regulation to a matched servomotor. In factory automation, it provides the intermediary power stage required for pick-and-place axes, packaging feeders, and other coordinated motion tasks.

The drive accepts an AC mains range of 110–230 V and internally converts it to a regulated DC link that must remain below the maximum of 450 V DC. A nominal phase current of 3 A rms can be supplied to the motor windings, set by pulse-width modulation at a carrier of 8 kHz to minimize audible noise. Dynamic braking energy is dissipated by an integral 66 Ω resistor, reducing the need for an external chopper when decelerating light to medium inertia loads. The 70 mm width and 171 mm depth help conserve panel space, while a residual bus drop of 4 V keeps conduction losses low. At rated output, the electronics generate 35 W of heat and only 12 W at idle, figures compatible with natural-convection enclosures when airflow is guided past the heat sink.

When the DC link climbs to 455 V DC, the drive executes an automatic shutdown to protect the bus capacitors and connected hardware. Motor coil pairing is subject to a minimum inductance of 4.3 mH; selecting windings below this value would raise current ripple beyond the device’s filter capability. The integrated functional safety layer provides STO, so torque-producing power can be interrupted without adding external relays. Under continuous duty, the converter draws up to 1.1 kVA from the supply, a figure useful for branch circuit sizing and energy budgeting.
