Product Description:
The SP12000-000000 is a digital servo drive produced by Kollmorgen for the SP Servostar Servo Drives series. It connects a three-phase 230 VAC mains supply to brushless motors, supplying regulated current so motion controllers can command torque and velocity with precise feedback. The device serves as a compact power stage in machine tools, packaging lines, and other industrial automation cells.
The drive provides a continuous power output of 7.3 kW when supplied by a three-phase 230 VAC line. During steady operation, it delivers a rated motor current of 20 A through pulse-width modulation switching at 8 kHz. The current command path uses an analog rail of ±15 VDC, from which the electronics draw 450 mA. Digital logic is isolated on a separate 8 VDC supply that requires 0.2 A. Fine torque resolution is supported by a motor-current ripple frequency of 16 kHz. Protection circuitry opens the power stage if the heat sink temperature reaches 118 °C or if the DC bus exceeds 430 VDC. The module is 202 mm deep and 264 mm high, allowing it to fit within compact multi-axis cabinet layouts.
To handle short-term load surges, the output stage can supply 40 A for up to two seconds. Internal losses generate heat, and the drive dissipates 240 W, which must be removed through panel ventilation or forced-air cooling. During normal operation, the drive disconnects if the DC-bus voltage drops to 125 VDC, preventing unstable control as the available supply declines. At power-up, the low-voltage cutoff is 255 VDC, which prevents operation before the DC bus reaches the required starting level. Motor windings and cables should be selected for the drive’s continuous and short-term current demands. Cabinet airflow must also provide enough cooling to remove the generated heat while keeping the drive below its shutdown temperature.
