Product Description:
The L+M-SERVOSTAR 606-AS-FAN is a servo drive manufactured by Kollmorgen for the S600 Servo Drives series. It modulates three-phase power to supply matched permanent-magnet motors with accurately regulated current, allowing precise velocity and position control in conveyor sections, packaging axes, and pick-and-place equipment. The device mounts inside a control cabinet and includes a dedicated fan for internal cooling, making it suitable for continuous industrial duty where panel temperatures can rise during prolonged motion cycles.
An auxiliary logic rail of 24 VDC keeps the control electronics active even when mains power is interrupted. The power stage delivers a continuous output of 6 A RMS and handles short-term surges of up to 12 A RMS during acceleration or shock loading. A pulse-width-modulated bridge switching at 8 kHz synthesizes near-sine motor currents, while dissipation at rated current is limited to 60 W, requiring the fan to sustain sufficient airflow. The output circuit supports motor windings from 7.5 mH to 40 mH, allowing low- or medium-inductance stators to operate without excessive current ripple or instability.
The housing carries an IP20 rating, which prevents accidental contact with live parts while allowing installation inside a protected cabinet. Connected to a three-phase supply, the inverter draws up to 4 kVA of installed load, a value that can be used for breaker and cable sizing. Residual conduction through the output stage is limited to 5 V, which reduces heat during motor standstill. Acoustic output remains below 45 dB(A) because the built-in fan moves air across the heat sink. Quiescent power dissipation is 15 W, and the output current has a form factor of 1.01. The analog input has a resistance of 20 kΩ to analog ground. A restart lock blocks automatic re-energization after faults, helping prevent unexpected motor movement when the system returns to an operational state.
