SP10600-504A2 by Kollmorgen

The SP10600-504A2 is a digital servo amplifier from Kollmorgen that belongs to the SP Servostar Servo Drives series. It interfaces between a motion controller and a permanent-magnet servo motor, converting commanded velocity or torque references into precisely modulated PWM output. In automated packaging lines, printers, or assembly cells, this drive regulates stator current so the attached motor produces the commanded mechanical response without overshoot or drift.

Continuous power is available at two supply levels: 1.1 kW when the module is connected to a 115 VAC single-phase source and 2.2 kW when it is connected to a 230 VAC three-phase line. Under either supply, the drive can furnish a rated output of 6 A RMS; for rapid acceleration, it tolerates 12 A for two seconds before current foldback engages. A PWM carrier of 16 kHz balances acoustic noise with switching losses, while motor current ripple is limited by an internal reconstruction frequency of 32 kHz. Command signals enter through an analog input that scales motor current at 1.70 A/V, and a complementary 2.12 A/V feedback path lets the controller close an external torque loop if required. The front-end analog circuits are powered by ±15 V DC at 320 mA, and the control logic core is supplied by an 8 V DC rail that draws 0.2 A.

Thermal and electrical safeguards support reliable operation. Steady losses result in 84 W of internal dissipation, so cabinet airflow must remove this heat. An overtemperature latch isolates the output when the heat sink reaches 118 °C, and an overvoltage trip disconnects the DC link at 430 V DC. During startup, the power-up undervoltage monitor prevents PWM operation until the link voltage exceeds 90 V DC. This startup interlock blocks gate commands below the enable threshold, preventing unstable motor current while the DC link is charging.
