Product Description:
The S30361-IO is a servo drive module produced by Kollmorgen as part of the S300 Servo Drives series. Designed for integration into distributed motion platforms, the unit regulates torque and velocity while supplying extra field I/O for the host controller. By combining its power stage with onboard digital expansion, the drive simplifies wiring in machines that require synchronized motion and localized sensor or actuator interfacing within an industrial automation cell. It connects directly to 110–230 V mains and routes feedback through the system bus. This arrangement helps the axis exchange discrete machine signals without requiring a separate remote I/O block near the drive.
In the I/O section, the drive accepts 14 digital inputs and 8 outputs, wiring sensors or relays directly to the axis hardware. The microprocessor scans addresses every 4 ms, so new field events reach the S300 bus with limited latency. Each input draws 24 VDC / 7 mA, letting PNP switches connect without buffers. Outputs change state within 10 ms, suiting gate, clamp, or light-stack duties. The internal logic rail can source 100 mA, powering a few low-current devices from the same 24 V line. This arrangement supports limit switches, presence sensors, and other simple status devices that need direct interaction with the motion axis.
Electrical performance aligns with the power stage of the S300 family. The DC link can rise to 450 VDC when the unit is operated on a three-phase 230 V supply, and the drive can deliver a continuous 3 A rms with peaks up to 9 A for acceleration events. Input power tops at 1.1 kVA, so a 4 AT fuse protects the auxiliary supply line while the MiniCombicon 12-pin plug carries the field wiring. A switching frequency of 8 kHz balances acoustic noise and motor current ripple, and Safe Torque Off (STO) is built in for immediate energy removal during an emergency stop. The enclosure measures 70 mm wide and 171 mm deep without connectors, allowing high-density installation beside other S300 modules. This compact format suits multi-axis cabinets where several drives must fit in a limited mounting area.
