Product Description:
The S30661-FB servo drive is produced by Kollmorgen as part of the S300 Servo Drives series. It serves as a single-axis controller that supplies closed-loop power to synchronous or induction motors, enabling motion axes in packaging machines, handling modules, and machining cells to follow commanded speed and torque profiles within an automated line. This arrangement supports accurate motor control during positioning, speed regulation, and repeated production cycles.
The drive accepts a single- or three-phase supply between 110–230 V AC; this window allows a standard control transformer to feed the unit without extra conversion hardware. Under this input, the power stage is rated for 2.4 kVA, which sets the apparent power level that cabinet wiring and protective devices must handle. It can deliver up to 6 A rms of continuous motor current, letting medium-frame servomotors accelerate without current foldback. Current is switched at 8 kHz, a frequency that balances audible noise with semiconductor heating. During rapid deceleration, the integrated brake resistor absorbs 80 W to keep the DC bus within limits. For feedback devices, an auxiliary regulator provides 300 mA so incremental or absolute encoders remain energized even when the power stage is idle. Two analog inputs, four digital command lines, and two digital outputs link the unit to a PLC or supervisory controller.
The control logic includes a dual-channel STO circuit certified to SIL2, allowing immediate torque removal without an external contactor. Internally, the rectifier and capacitors withstand up to 450 VDC, accommodating regenerated energy when the mains reach the upper limit. A secondary 5 VDC encoder feed supports redundant position transducers. Mechanical size is limited to 70 mm in width, 246 mm in height, and 171 mm in depth before connectors, so several drives can mount side by side in a shallow panel. The housing provides basic protection, while the Safe Torque Off architecture simplifies compliance with functional safety requirements.
