Product Description:
The SERVOSTAR-606-AS-FAN servo drive is manufactured by Kollmorgen and is part of the S600 Servo Drives series. The module functions as a power amplifier for brushless AC motors, translating commanded motion profiles into controlled current waveforms that keep the shaft synchronized with feedback signals. By integrating control electronics, power semiconductors, and fault monitoring in a single housing, it streamlines cabinet layouts for packaging lines, automated assembly systems, and material-handling axes that require deterministic positioning.
The drive uses a separate auxiliary logic rail of 24 VDC, and this rail is protected by an internal auxiliary fuse rated at 3.15 AT. Incoming three-phase supply conductors must be protected with a 10 AT AC supply fuse, and the built-in brake chopper branch has separate fuse protection to isolate faults in the dynamic-braking circuit. During acceleration spikes, the power stage can deliver a peak output of 12 A rms, while continuous thermal losses are limited to 60 W. The current loop remains stable when the connected motor has a minimum load inductance of 7.5 mH and stays within safe switching limits up to 40 mH. This operating range supports short, high-frequency torque commands without saturating the filter network or tripping overcurrent sensors.
For long-term loading, the supply section is sized for 4 kVA, and the current channel provides a steady-state output of 6 A rms to the motor windings. An internal brake resistor of 33 Ω absorbs regenerated energy, and it is actively cooled by a cabinet fan that engages when the ambient temperature reaches 58 °C. The housing measures 70 mm wide, 265 mm deep, and 275 mm high, which supports dense side-by-side mounting on DIN rails. The unit weighs 4 kg, making it suitable for compact cabinet installations. Its rigid housing also supports use in vibration-prone installations with frequent start-stop duty.
