SP10600-443B2 by Kollmorgen

The SP10600-443B2 servo amplifier is manufactured by Kollmorgen and belongs to the SP Servostar Servo Drives series. It is an AC inverter that converts a three-phase 230 VAC mains feed into regulated current for brushless servomotors, allowing tight torque and velocity control for pick-and-place actuators, gantry stages, and other industrial axes. Analog command channels and digital feedback interfaces let the unit close the current loop inside the drive, reducing the controller load while maintaining fast response times.

Under rated conditions, the drive delivers a continuous phase output of 6 A RMS, while a peak output of 12 A can be sustained for 2 seconds to overcome inertia or friction during acceleration. With a 230 VAC three-phase supply at 45 °C, the available continuous mechanical power reaches 2.2 kW. Pulse-width modulation operates at 16 kHz, and the resulting motor current ripple is centered around 32 kHz, keeping acoustic noise and torque ripple low. The ±10 V velocity and torque inputs are scaled at 1.70 A/V, and the current feedback path returns 2.12 A/V to the controller for diagnostic and tuning purposes. Control electronics draw 0.2 A from an 8 VDC logic rail, while the analog interface consumes 320 mA from its isolated supply, keeping signal integrity independent of power-stage loading.

The enclosure has an internal heat dissipation of 84 W, and convection or forced-air cooling must keep the components within their temperature limits when the ambient temperature reaches 45 °C. The unit maintains full ratings at elevations up to 3300 ft without derating. A temperature sensor triggers a shutdown at 118 °C to protect the power semiconductors. DC bus monitoring removes the gate drive if the voltage exceeds 430 VDC or falls below 90 VDC. An overvoltage trip also protects the link capacitors from excessive voltage during regenerative braking.
