Product Description:

The S30361-PB is an S300 servo drive produced by Kollmorgen for the S300 Servo Drives series. The unit functions as a compact motion controller that accepts command signals from a higher-level PLC and supplies regulated three-phase power to a matched servo motor. By controlling torque, speed, and position in real time, it forms the active interface between the motion controller and the mechanical load in automated assembly, inspection, and material-transfer equipment.

At the power input, the drive operates on a single-phase or three-phase supply of 110 to 230 V, draws a maximum apparent power of 1.1 kVA, and delivers a continuous output of 3 A rms to the motor. Short-term overloads are handled with a peak phase current of 9 A rms, while the internal DC link may rise to 450 VDC during regeneration. The IGBT bridge switches at a nominal 8 kHz, a rate that balances acoustic noise with switching losses, and a reduced 16 kHz mode can be selected for quieter operation. Communication and expansion are provided by a PROFIBUS option card that offers two 9-pin Sub-D ports and supports network speeds up to 12 MBaud. Current regulation follows a form factor of 1.01, the output stage shows a residual voltage drop of 4 V, and the device may be energized up to 30 cycles per hour without exceeding thermal limits.

Thermal management is straightforward because the unit releases 12 W when enabled but idle and 35 W under rated load, so cabinet ventilation can be sized with modest airflow. Integrated STO (Safe Torque Off) removes energy from the motor phases without cutting mains power, which supports Category 0 stop requirements. Mechanical installation is simplified by the aluminum chassis, which weighs only 2.6 kg, easing mounting on DIN rails or backplates and keeping added mass low on mobile machinery.
