Product Description:
The S30101-SE is a servo drive produced by Kollmorgen and belongs to the S300 Servo Drives series. It is intended to regulate torque, speed, and position of brushless servo motors in automated machinery, translating low-level control commands into three-phase power that the motor can use. By integrating power conversion, feedback processing, and safety circuitry in one compact module, the unit helps machine builders implement tightly synchronized multi-axis motion without designing custom power stages.
During continuous operation the drive supplies a rated phase current of 1.5 A RMS, yet it can reach a peak output of 4.5 A RMS for short acceleration intervals, giving axes headroom for rapid indexing. The converter accepts a mains window of 208–480 V three-phase, rectifies it, and charges a DC bus that may rise to 900 VDC; this wide span lets a single part number cover multiple plant voltages. An output stage switching at 8 kHz modulates the bus energy into sinusoidal motor waveforms, keeping acoustic noise low and current ripple confined. With a nominal input demand of 1.2 kVA the unit fits comfortably on 10 A supply circuits, easing cabinet fuse sizing. Two analog command channels, four digital inputs, and two digital outputs are provided so motion functions can be tied directly to PLC sequences without extra I/O cards.
The electrical profile is backed by functional safety and thermal design. The integrated STO (Safe Torque Off) circuit removes motor power through solid-state means, allowing Category 3 stop functions without external relays. Excess kinetic energy is routed to an internal resistor that dissipates 40 W, matching the rated heat loss for consistent enclosure temperature. A plug-in SERCOS interface card synchronizes velocity loops over a deterministic fiber ring, supporting real-time networking alongside other Kollmorgen axes. Mechanical dimensions of 70 mm width and 171 mm depth leave enough clearance for airflow when drives are stacked side by side in narrow panels.
