Product Description:

The SP10300 belongs to the SP Servostar Servo Drives series from Kollmorgen. It is a digital servo amplifier that conditions three-phase mains power and command signals so a brushless servomotor can execute precise velocity, torque, or position profiles in automated machinery. By pairing the drive’s control logic with a downstream encoder loop, the unit supplies regulated current to the motor phases and forms the active axis interface between higher-level motion controllers and mechanical loads.

On a 230 VAC three-phase supply, the drive can deliver 1.1 kW of continuous mechanical power, while its rated output current is 3 A. Analog velocity or torque commands enter through a differential input that converts every volt into 0.85 A/V of current demand, while feedback is returned to the regulator at 1.06 A/V for stable closed-loop gain. The analog interface is powered by a ±15 VDC rail that draws 200 mA, and all digital logic is supported by an internal 8 VDC bus at 0.2 A. The switching devices operate at a carrier frequency of 16 kHz, while the output stage modulates motor current at 32 kHz to keep ripple outside typical mechanical bandwidths. The form factor does not exceed 1.01, allowing the module to fit inside dense control cabinets without exceeding standard depth limits.

During brief acceleration bursts, the current regulator can supply 6 A for two seconds before thermal limits take effect. The inverter dissipates 37 W as heat under nominal conditions and trips if the substrate temperature reaches 118 °C. DC-link faults are managed by an overvoltage shutdown at 430 VDC and an undervoltage cutoff at 90 VDC, protecting both the IGBTs and the connected motor. These thresholds allow the drive to respond to incoming power fluctuations and regenerative events that temporarily raise or lower the bus voltage. The current and temperature protections also prevent the output stage from operating beyond its allowable limits during demanding motion cycles.
